Mouse anti Human CD4 FITC - CD26 PE

Identification of CD4 on Human helper/inducer T cells expressing the 60,000 M.W. surface antigen (HLA class II reactive). CD4 is present in low density on monocytes. Anti-Human CD28 binds the 44kDa MW cell surface protein on the surface of most T cells. The CD26 antigen recognizes the enzyme dipeptidyl peptidase (DPP), a serine protease. Its M.W. is 120 kDa. The CD26 antigen is associated with the binding of the TAT transactivating protein of the Human immunodeficiency virus (HIV).

PBMC: Add10 µL of MAB/10^6 PBMC in 100 µL PBS. Mix gently and incubate for 15 minutes at 2º to 8ºC. Wash twice with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze. WHOLE BLOOD: Add10 µL of MAB/100 µL of whole blood. Mix gently and incubate for 15 minutes at room temperature 20ºC. Lyse the whole blood. Wash once with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze. See instrument manufacturer’s instructions for Lysed Whole Blood and Immunofluorescence analysis with a flow cytometer or microscope.
