Application Details

Application Notes: Optimal working dilution should be determined by the investigator.

Assay Procedure:

• Take 100 μL peripheral blood anticoagulated by EDTA and add to the bottom of 5 mLtube,
• Add appropriate amount of antibody to the bottom of flow tube mixing with the whole blood, incubate for 30 minutes at room temperature,
• Add 2 ml1×RBC lysis buffer, incubate for 10 minutes after mixing, dissolve red blood cells (recommended: RBC lysing Solution 10×,Cat.: FXP001),
• Sample tube is set to 1000 rpm centrifugation for 5 minutes, discard the supernatant,
• Add 2 mLPBS wash buffer to resuspend the cells, then 1000 rpm centrifugation for 5 minutes, discard the supernatant,
• Add appropriate amount of fluorescent-labeled Streptavidin and incubate for 20 minutes away from light at room temperature.
• Repeat step 5.
• Add 0.5 mLPBS wash buffer to resuspend the cells and detect by flow cytometry (sample should be determined on the day on the machine and can also be added fixation overnight at 4 °C then measured).
• [PBS wash buffer: PBS +1 % FBS +0.1 % NaN3, Cat.: FXP005]
• [Cell fixation: 2 % formaldehyde solution]

Target Details for CD8

Target: CD8

Alternative Name: CD8 (CD8 Products)

Background: This molecule is expressed on the T suppressor/cytotoxic cell population (which comprises about 1/3 of the peripheral blood T lymphocytes total population) and with most of thymocytes, as well as a subset of NK cells. CD8 expresses as either a heterodimer with the CD8b chain (CD8ab) or as a homodimer (CD8aa or CD8bb). CD8 acts as a co-receptor with MHC Class I restricted TCRs in antigen recognition. CD8 function is important for positive selection of MHC Class I restricted CD8+ T cells during T cell development.
