Flow Cytometry Product Notes:
Test Sizes: To accommodate multicolor flow cytometry, eBioscience is in the process of reducing test size volumes from 20 µl to 5 µl. Please check your antibody vial for the recommended test size.
Fluorochrome Replacements: eBioscience is in the process of replacing all Pacific Blue® and APC-Alexa Fluor® 750 conjugated products with eFluor™ 450 and APC-eFluor™ 780 conjugated products, respectively. |

Description
The R22/7 monoclonal antibody reacts with the amino terminus of human CCR5 (CD195), an approximately 45 kDa member of the G protein-coupled receptor (GPCR) superfamily that binds chemokines including MIP-1a, MIP-1ß and RANTES. Human CCR5 is expressed on resting T cells with a memory/effector phenotype, monocytes, macrophages and immature dendritic cells. CCR5 functions as a receptor to direct the chemotaxis of lymphocytes, and is the primary co-receptor for macrophage-tropic Human Immunodeficiency Virus Type 1 (HIV-1), which binds CCR5 through gp120.
Applications Reported
For research use only, not for diagnostic or therapeutic use. This R22/7 antibody has been reported for use in flow cytometric analysis.
Applications Tested
This R22/7 antibody has been pre-titrated and tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at 20 μl (0.125 μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume).
Special Notes
R22/7 stains with lower intensity on human peripheral blood mononuclear cells, than on human lysed whole blood. For staining human peripheral blood mononuclear cells, we recommend the use of clone eBioT21/8 (cat.
1957).
