Available Formats Rabbit IgG/kappa; Mouse IgG2a/kappa with NullFc™ (compatible with traditional anti-mouse secondary reagents); Biotinylated rabbit Fab with a single defined biotin and His-tag at the C-terminus of the heavy chain
Host Species Rabbit
Immunogen Human CD38 (accession D84276) recombinantly expressed on HEK293 cells
Verified Reactivity Human, Cynomolgus (non-human primate)
Verified Applications Flow Cytometry
Concentration 0.5 – 1.0 mg/ml
Production Transient transfection expression system in mammalian HEK293 cells
Purification Protein A affinity chromatography (MAb), Immobilized metal ion chromatography (Fab)
Formulation PBS pH 7.2 with 0.08% sodium azide
Storage 4° C for up to 3 months, for longer storage aliquot and store at -20° C
Target CD38
Alternate Names ADPRC1
Target Description CD38 is a type II transmembrane protein found on the surface of many immune cells including T cells, B cells, myeloblasts and NK cells. CD38 functions as both a receptor and an enzyme. CD38 can bind to CD31 on T cells resulting in the production of various cytokines. Enzymatically, CD38 functions as a cyclic ADP ribose hydrolase.
