CD38 is a type II transmembrane glycoprotein of 45 kDa with a protein core of 35 kDa. The CD38 antigen is expressed on essentially all pre-B lymphocytes, plasma cells, and thymocytes. It is also present on activated T lymphocytes, natural killer (NK) lymphocytes, myeloblasts, and erythroblasts. The antigen is expressed during the early stages of T- and B-lymphocyte differentiation, is lost during the intermediate stages of maturation, and then reappears during the final stages of maturation. The CD38 antigen is expressed on 90% of CD34 cells, and is not expressed on pluripotent stem cells. Coexpression of CD38 antigen on CD34 cells indicates lineage commitment of those cells. CD38 is a counter-receptor of CD31. It is also expressed in T- and B-acute lymphoblastic leukemia (ALL), Burkitts lymphoma, multiple myeloma, acute myeloid leukemia (AML), and chronic lymphocytic leukemia (CLL). The OKT10 directed against human CD38 antigen.
Each lot of these antibodies has been pre-titrated and tested by flow cytometric analysis of human PBMCs such that 0.5μg (unconjugated, Biotin) or 5μl (conjugated) of these products are sufficient for staining 1 million cells in a 100μl staining volume or 100μl of whole blood. It is recommended to titrate antibody reactivity empirically for optimal performance. Non-human primate cross-reactivity has been validated using Caprico’s purified and PE, APC, and Biotin conjugated clone OKT10 products. Do you need an antibody for an antigen you don't see on our website? Do you need a different conjugation than what we have listed? We have a wide selection of antigens with a variety of conjugations available. Please reach out to us at [email protected].
