Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of MJ cells using CD25/IL2RA Recombinant antibody (83896-1-RR)

    WB analysis of MJ using 83896-1-RR (same clone as 83896-1-PBS)

    MJ cells were subjected to SDS PAGE followed by western blot with 83896-1-RR (IL2RA antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83896-1-PBS in a different storage buffer formulation.

Background Information

Proliferation of T lymphocytes is triggered by the interaction of IL-2 with its specific receptor following T lymphocyte activation. The receptor for IL-2 has three forms, generated by different combinations of three different proteins, the alpha chain (IL-2R alpha), the beta chain (IL-2R beta), and the gamma chain (IL-2R gamma) (PMID: 8476561). IL-2R alpha (also known as CD25) is a type I transmembrane protein present in activated T cells, activated B cells, some thymocytes, myeloid precursors, and oligodendrocytes. CD25 is also found on natural CD4+ Foxp3+ Treg cells (PMID: 22585674).
