What are Th17 cells?
Th17 cells are a subset of T helper cells that play a significant role in autoimmune diseases and inflammation.
How is cell purity measured?
Cell purity is typically measured using flow cytometry, which allows for the analysis of specific cell populations based on surface markers.
What is the significance of achieving 90% purity?
Achieving high purity is crucial for ensuring the reliability of experimental results and for studying the specific functions of Th17 cells.
Can this method be used for other T cell types?
While this protocol is optimized for Th17 cells, similar methods can be adapted for other T cell subsets with appropriate modifications.
What role do small molecular inhibitors play in this protocol?
