Laboratories studying parasites, nematodes, and other multicellular organisms often need to evaluate several experimental conditions at the same time. A typical study may involve exposing organisms to different compounds and then measuring changes in their behavior or survival. As the number of test conditions increases, managing individual samples can become more difficult.

A multi-well format provides a practical way to organize these experiments. Instead of handling every sample separately, researchers can work with multiple wells in a single plate. This makes it easier to test different treatments under comparable conditions and evaluate responses across a larger number of samples.

However, the benefits of a multi-well format can be reduced if researchers still need to perform numerous separate transfers or move organisms between different containers during the experiment. Each additional handling step can make the workflow more time-consuming and harder to keep consistent.

The Multi Well Strainer is designed to address this type of workflow challenge by combining cell propagation with size separation in a multi-well format. The PluriCell product line uses nylon-mesh strainer plates that fit into a range of multi-well plates from different manufacturers. The system is designed to provide a ready-to-use setup for culturing and testing single- or multicellular organisms.

For parasite and nematode assays, this integrated format can help researchers organize treatment and observation within a structured multi-well system. The strainer plate and well tray work together, allowing organisms to be placed in wells, exposed to a target compound, and then evaluated based on their migration.

Rather than focusing only on filtration, the Multi Well Strainer brings size separation into a format that can support broader experimental workflows.

What Makes Parasite and Nematode Assays Different?

Parasite and nematode studies can involve organisms that behave differently from the cell samples used in many conventional laboratory assays. In addition to determining whether an organism survives a treatment, researchers may need to observe how it moves or responds to changes in its environment.

This makes the organization of the experimental setup particularly important.

Working With Multicellular Organisms

The PluriCell system is designed for culturing and testing single- or multicellular organisms. Its multi-well strainer plates can therefore support experiments involving parasites, nematodes, and other organisms that need to remain within a defined well during treatment.

Keeping the organisms within an organized well-based system allows researchers to manage several experimental conditions at the same time.

Using Migration as a Measurement

For some parasite and nematode assays, movement provides an important measure of the response to a treatment. The Multi Well Strainer system allows researchers to transfer organisms into the wells, treat them with a target compound, and measure their migration. The strainer plate and well tray work together to create the setup needed for this type of experiment.

This provides a way to observe biological responses without requiring researchers to move the organisms repeatedly between separate experimental containers.

Comparing Multiple Conditions

Multi-well experiments are particularly useful when researchers need to compare several conditions. Different wells can be used for different compounds, concentrations, controls, or experimental groups. Because these conditions can be arranged within the same plate-based workflow, researchers can organize comparisons more easily.

For larger screening programs, this approach can help laboratories manage multiple experimental conditions while maintaining a consistent format.

Where Conventional Multi-Well Workflows Become Difficult

Multi-well plates already provide an efficient way to organize experiments, but the workflow can become more complicated when researchers need to repeatedly transfer organisms or samples between different containers.

Repeated Sample Transfers

Moving organisms between separate containers adds handling to the experimental process. When many samples are involved, these transfers can take considerable time.

They may also make it more difficult to maintain identical procedures across every experimental group. Researchers need to repeat the same handling steps for each sample, which can increase the workload as the number of wells grows.

Managing Many Individual Wells

High-throughput experiments depend on careful organization. When researchers are working with many wells, they need to keep track of which organisms, compounds, and treatments belong to each location.

A structured multi-well system can make this easier by keeping experimental groups arranged within a defined plate format.

Maintaining Comparable Conditions

Comparing treatment groups requires researchers to maintain similar experimental conditions wherever possible.

Differences in handling, transfer procedures, or sample placement can make comparisons more difficult. Using a consistent system across the experiment helps reduce unnecessary differences between wells.

Moving Between Culture and Measurement

An assay may involve several stages, from placing organisms into wells to treating them and measuring their response.

If these stages require repeated movement between separate containers, the workflow becomes more complicated. An integrated setup can help reduce the number of transitions between different pieces of laboratory equipment.

How the Multi Well Strainer Combines Culturing and Size Separation

The Multi Well Strainer is part of the PluriCell product line, which was developed to combine cell propagation with size separation.

The system uses nylon-mesh strainer plates that fit into a wide range of multi-well plates from different manufacturers. The current format is available for 6-well and 12-well plates.

An Integrated Strainer and Well System

The strainer plate and well tray fit together to create a ready-to-use system. This arrangement allows researchers to work with organisms within a structured multi-well environment while also incorporating size separation into the experimental setup.

The design is particularly relevant when the size of the organisms or material being studied is part of the workflow.

Nylon Mesh for Size Separation

The current Multi Well Strainer is available with 72 µm and 210 µm mesh sizes. These options provide researchers with different size-separation choices depending on the organisms or material involved in the experiment. The product information also indicates plans to expand the available range to mesh sizes between 5 µm and 500 µm.

This future expansion could provide laboratories with additional flexibility for different experimental requirements.

Supporting Culturing and Testing

The system is not limited to filtration as an isolated step. Its purpose is to combine cell propagation with size separation and provide a setup for culturing and testing single- or multicellular organisms.

For parasite and nematode research, this means the same multi-well format can be incorporated into experiments where organisms are treated and their movement or response is subsequently measured. This integrated approach can help laboratories keep experimental procedures organized while reducing the need to rely on multiple separate setups.

Supporting High-Throughput Parasite and Nematode Testing

The multi-well format becomes especially useful when researchers need to test several parasite or nematode samples under different conditions. Instead of treating each organism group as a completely separate experiment, researchers can organize multiple treatments within the same plate.

The Multi Well Strainer provides a structured setup for these experiments. Organisms can be transferred into the wells, exposed to the target compound, and then assessed according to the response being studied.

Testing Multiple Conditions in Parallel

High-throughput experiments often involve comparing several treatment conditions. Different wells can be assigned to different compounds or experimental groups, allowing researchers to perform multiple tests within the same overall setup.

This arrangement makes it easier to compare responses because the experimental groups remain organized within the same multi-well format.

Applying Target Compounds

The PluriCell system can be used for assays in which parasites, nematodes, or other multicellular organisms are treated with a target compound.

Researchers can place the organisms into the wells and apply the treatment according to their experimental design. The organisms can then be observed to determine how they respond.

Keeping the treatment stage within the multi-well setup helps create a straightforward workflow for experiments involving multiple conditions.

Measuring Responses Across Wells

After treatment, researchers can measure organism migration to evaluate the effect of the target compound.

Because multiple experimental groups can be arranged across the same plate, researchers can compare migration between treated and untreated conditions or between different treatment groups.

The organized format makes the experiment easier to manage when the number of conditions increases.

Measuring Paralysis, Cytotoxicity, and Death

The Multi Well Strainer and well tray are designed to provide a ready-to-use system for assays measuring paralysis, cytotoxicity, and death of multicellular organisms.

These applications make the system relevant to studies where researchers need to evaluate how a target compound affects parasite or nematode behavior or survival.

Measuring Paralysis

A treatment may affect the movement of an organism without immediately resulting in death. In such experiments, observing migration can provide a way to assess the response.

The multi-well setup allows researchers to expose organisms to the target compound and subsequently measure their movement within the experimental system.

Evaluating Cytotoxicity

The system can also support assays that examine cytotoxic effects on multicellular organisms.

Researchers can compare organisms exposed to different treatments and evaluate their responses using the selected assay procedure. Maintaining a consistent multi-well format helps keep the experimental groups organized during testing.

Assessing Death

Death is another response that can be measured using the system. Researchers can treat organisms with a target compound and evaluate the resulting biological response.

Because the same basic setup can be used across multiple wells, researchers can compare different experimental conditions within a single organized workflow.

Why Consistent Setup Matters

Whether the endpoint is paralysis, cytotoxicity, or death, researchers need to compare experimental groups under controlled conditions.

Using the same type of well and strainer arrangement across the experiment provides a consistent physical setup for the different groups. This can make it easier to organize observations and compare the resulting measurements.

Choosing the Right Mesh Size and Well Format

The appropriate configuration of a multi-well system depends on the organisms being studied and the experimental design. The current PluriCell Multi Well Strainer is available with two nylon mesh sizes: 72 µm and 210 µm.

Selecting the Mesh Size

The two available mesh sizes give researchers options for different size-separation requirements. A researcher can select the mesh that is appropriate for the organisms or material being handled in the assay. The choice should be based on the requirements of the specific experiment rather than assuming that one mesh size will suit every application.

The product information also indicates plans to expand the available mesh range from 5 µm to 500 µm, which would provide additional options for future applications.

Selecting the Well Format

The Multi Well Strainer is currently available for 6-well and 12-well plates.

These formats allow researchers to select a plate configuration according to the number of experimental groups they need to test.

The product information also indicates plans to include 24-well and 48-well formats in the future. Additional well formats could provide laboratories with more options for experiments involving larger numbers of conditions.

Compatibility With Different Plate Manufacturers

The strainer plates are designed to fit a wide range of multi-well plates from different manufacturers. This flexibility can make it easier for laboratories to incorporate the system into existing multi-well workflows rather than changing their preferred plate format or supplier.

Conclusion
