- Extra Details:
- CD152, also known as CTLA-4, is homologous to the costimulatory molecule CD28. Like CD28, the CD152 molecule binds the family of B7 counter-receptors (CD80/B7-1 and CD86/B7-2) on antigen-presenting cells. CTLA-4 is not expressed on resting T lymphocytes but is induced 2-3 days following T-cell stimulation via the T cell receptor (TCR) complex. Whereas CD28 provides a positive costimulatory signal, CD152/CTLA-4 is a negative regulator of T-cell activation, possibly by inhibiting tyrosine kinase signalling through the TCR through its association with tyrosine phosphatases such as SHP-2. Applications: Suitable for use in Flow Cytometry, ELISA, and Immunoprecipitation. Other applications not tested. Recommended Dilution: Flow Cytometry: ≤ 3ug/10e6 cells Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
