简介：
Overview
This protocol enables researchers to assess lymphocyte mobility in vitro by utilizing a transmigration system. Lymphocytes are placed in the top chamber, while chemokines in the bottom chamber induce migration along a gradient.
Key Study Components
Area of Science
- Immunology
- Cell Biology
- Transmigration Studies
Background
- Lymphocyte transmigration is crucial for immune responses.
- This protocol allows for the assessment of various chemokines.
- It can be used to evaluate inhibitors or therapies targeting chemokine pathways.

What is the main advantage of this protocol?
The protocol allows researchers to assess the effectiveness of various chemokines in inducing lymphocyte migration in a controlled environment.
How long does the experiment take?
The lymphocytes are counted after 48 hours of incubation in the transmigration system.
Can this method be used for other cell types?
While this protocol focuses on lymphocytes, it may be adapted for other cell types that respond to chemokines.
What tissues are used for lymphocyte isolation?
Lungs and spleens from euthanized mice are typically used for isolating lymphocytes.
Is this method suitable for testing therapeutic agents?
Yes, the protocol can be used to test inhibitors or biologic therapies targeting specific chemokine pathways.
