CD40 is a glycoprotein important for T-B lymphocytes interactions. The ligand for CD40 is CD154 (CD40L). The function of CD40 is involved in growth, differentiation, and isotype-switching on B cells and also involved to rescue B cells from apoptosis. CD40 is a 48 KD type I single chain trans- membrane glycoprotein expressed on normal and neoplastic B cells, but not on terminally differentiated plasma cells. CD40 antigen is also present on Hodgkin's and Reed-Sternberg cells, follicular dendritic cells, some macrophages, basal epithelial cells and endothelial cells.
Suitable for use in Flow Cytometry. Other applications not tested.
Flow Cytometry: Neat; use 20ul/100ul whole blood or 10e6 cells in suspension.
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. Dilute only prior to immediate use. Stable for at least 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.
