- Weitere Details:
- CD19 is a monomeric transmembrane glycoprotein expressed at relatively constant levels throughout B cell development from early pro-B/pre-B cells (i.e. B220+/CD43+/HSA+) through fully differentiated B cell stages.1-7 Terminally differentiated plasma cells do not express CD19.1 In humans, the CD19 molecule on the surface of mature B cells associates with CD21 (CR-2) and CD81 (TAPA-1), and this multimolecular complex synergizes with surface immunoglobulin to provide signal transduction and promote cellular activation.3, 4 All splenic and peritoneal IgM+ cells of both B-1 and B-2 lineages are CD19+, with B-1 cells expressing higher levels of CD19 than B-2 cells in these sites.1, 7 Recent studies with CD19-deficient mice have suggested that this molecule may not be required for normal generation and maturation of B cells in the bone marrow.7 Monoclonal antibody 6D5 recognizes the same epitope as the published clone, 1D3 (1). Applications: Suitable for use in Flow Cytometry, Immunoprecipitation and In vivo and in vitro functional studies. Other applications have not been tested. Recommended Dilution: Flow Cytometry: ≤ 1ug/10e6 cells Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
