Specifications
CD19 is a type I transmembrane glycoprotein and a member of the immunoglobulin superfamily. It is expressed at all stages of B cell differentiation except terminally differentiated plasma cells. It is also present on the cell surface of follicular dendritic cells. CD19 associates with CD21, CD81, Leu 13 and/or MHC Class II molecules to form a signal transduction complex on the B cell surface. This signaling complex modulates the activation threshold for the B cell antigen receptor (BCR).1-5
Applications:
• Flow cytometry
• Immunohistochemistry (frozen sections)
• Immunoprecipitation
Recommended Dilution:
Flow Cytometry: 10ul/10e6 cells
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20°C or colder. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
PE/CY5 combination conjugate is used as a third fluorochrome in multicolor flow cytometry applications when only a single 488nm excitation source is available. Antibodies are covalently coupled using heterobifunctional linking reagents, resulting in an optimal conjugation format for flow cytometry.
