CD38 is a 45kD type II single-chain transmembrane glycoprotein. It is found on immature cells of the B cell and T cell lineages, but not on most mature resting peripheral lymphocytes. It is also present on thymocytes, pre-B cells, germinal center B cells, mitogen-activated T cells, immunoglobulin-secreting plasma cells, monocytes, NK cells, and erythroid and myeloid progenitors in bone marrow. CD38 acts as a NAD glycohydrolase on T lymphocytes. Monoclonal antibodies against human and mouse CD38 have a wide range of biological effects, including the induction of B and T cell proliferation, protection of B cells from apoptosis, inhibition of B lymphopoiesis and enhancement of macrophage antigen presenting cell function (1-2).
Applications:
Suitable for use in Flow Cytometry, Immunohistochemistry and Western Blot. Other applications not tested.
Recommended Dilution:
Flow Cytometry: 5ul/10e6 cells
Immunohistochemistry: Frozen sections
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C before opening. DO NOT FREEZE! Stable at 4 degrees C as an undiluted liquid. Stable for 12 months at 4 degrees C. Freezing R-Phycoerythrin (PE) conjugates will result in a substantial loss of activity. PE conjugates are sensitive to light.
