Application Notes
Mik-beta 1 inhibited binding of iodine labelled IL-2 to YTS cells in a dose dependent manner. Mik-beta 1 also successfully immunoprecipitated beta chain of the IL-2R from radio iodinated YTS extract. Biotinylated Mik-beta 1 also efficiently competes with IL-2 for binding to solubilized beta chain. Flow cytometry was used to study the cellular disctribution of beta chain, as determined by mik-beta 1 staining. This antibody completely inhibited IL-2 dependent T cell growth in presence of anti-Tac. Two-color flow cytometric analysis using anti-beta chain mAbs clearly showed that approximately 10% of peripheral blood lymphocytes manifest the beta chain and that this population is mainly composed of Leu-19+ NK cells (PMID: 2467293). Mik beta 1 antibody acts synergistically with humanized anti-Tac to prevent IL-2-induced proliferation of activated T cells (PMID: 8335891). A recombinant single chain immunotoxin of Mik-beta 1 and Pseudomonas derived exotoxin PE40 was selectively cytotoxic for cells expressing high levels of IL-2R beta (p75) subunit (PMID: 1401913).
Short Description
This chimeric human antibody was made using the variable domain sequences of the original Mouse IgG2a format, for improved compatibility with existing reagents, assays and techniques.
