- Extra Details:
- Human CD4 is a cell surface glycoprotein of 55kD expressed on most thymocytes, on about two thirds of peripheral T cells, and on some monocyte macrophage lineage cells. CD4 interacts with MHC Class II molecules in an accessory role during foreign antigen recognition by T cells. The extracellular portion of CD4 is an array of four Ig-like domains. The amino terminal region of CD4 is a receptor for the HIV-1 viral protein gp120. Recognizes the domain 1 region of the CD4 molecule. Applications: Suitable for use in ELISA, Flow Cytometry and Immunohistochemistry. Other applications not tested. Recommended Dilution: ELISA: Capture Immunohistochemistry: Fixed cells or tissues Flow Cytometry: 5x10e5 cultured HPB-MLT human tumor cells were washed and incubated 45 min on ice with 80ul of anti-CD4 antibody at 5ug/ml. Cells were washed twice and incubated with Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 1.84 log10 fluorescent units when compared to a Mouse IgG1 negative control at a similar concentration. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
