For fluorochrome conjugated antibodies only, light exposure should be avoided. Use dim light during handling, incubation with cells, and prior to analysis. It is recommended that cells be analyzed within 18 hours of staining. If the reagent is being diluted, it is recommended that only the quantity to be used within one week be diluted.
Each lot is tested by flow cytometry using human peripheral blood leukocytes (PBL). Based on this testing it is recommended that 5 µL of antibody be used per 1 x 10^6 cells in a 100 µL staining volume.
CD8 molecule is composed of two chains termed alpha and beta. CD8 is found on a T cell subset of normal cytotoxic / suppressor cells which make up approximately 20 to 35% of human peripheral blood lymphocytes. The CD8 antigen is also detected on natural killer cells, 80% of thymocytes, on a subpopulation of 30% of peripheral blood null cells and 15 to 30% of bone marrow cells.
