Human CD38 is a type II transmembrane glycoprotein with bifunctional ectoenzyme activity catalyzing both synthesis and hydrolysis of cyclic ADP ribose (1). CD38 is involved in lymphocyte activation and adhesion to endothelium and has recently been identified as a counter-receptor of CD31 (2).
Applications:
Suitable for use in Flow Cytometry. Other applications not tested.
Recommended Dilution:
Flow Cytometry: 5x10e5 cultured Raji cells per tube were washed and incubated 45 min on ice with 80ul of anti-CD38 antibody at 5ug/ml. Cells were washed twice and incubated with Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 1.71 log10 fluorescent units when compared to a Mouse IgG1 negative control at a similar concentration.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
