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 CD4

Target: CD4

Alternative Name: CD4 (CD4 Products)

Background: CD4 is found on most thymocytes, a subset of T cells and at low level on monocytes/macrophages.CD4 is a co-receptor involved in immune response (co-receptor activity in binding to MHC class II molecules) and HIV infection (CD4 is primary receptor for HIV-1 surface glycoprotein gp120). CD4 regulates T-cell activation, T/B-cell adhesion, T-cell diferentiation, T-cell selection and signal transduction.

Pathways: TCR Signaling, Maintenance of Protein Location, CXCR4-mediated Signaling Events
