Human IL2 Receptor alpha ELISA Kit

Quantitative immunoassay kit from Antibodies.com for measuring human IL-2 Receptor alpha (CD25) levels in research samples.

The IL-2Rα subunit is the defining surface marker of activated T lymphocytes and regulatory T cells, contributing to interleukin-2 signal transduction and downstream JAK-STAT pathway activation.

Investigators use this product to study T cell activation states, immune regulation mechanisms, transplant tolerance, and autoimmune disease biology in human in vitro studies.

The microplate format supports ELISA workflows and includes pre-coated wells, biotinylated detection antibody, recombinant standard calibrators, streptavidin-HRP conjugate, substrate solution, and wash buffer.

Quality control testing verifies lot-to-lot consistency for the standard curve and detection reagents.

The kit supports cell culture supernatant analysis and translational immunology workflows where CD25 expression serves as a quantitative readout of lymphocyte activation status.
