Description

Armenian Hamster Monoclonal Antibody

Description: CCR5 is the major co-receptor for macrophage-tropic isolates of HIV-1. CCR5, also known as CD195, is a seven transmembrane chemokine receptor capable of binding RANTES, MIP-1 alpha and MIP-1 beta. Knockout mice show a decreased recruitment of macrophages and increased susceptibility to infection. Protein and mRNA has been found in macrophages from thioglycolate-treated and activated T cells. The HM-CCR5(7A4) monoclonal antibody binds the N terminal extracellular domain of mouse CCR5 with no crossreactivity to human CCR5. Applications Reported: This HM-CCR5 (7A4) antibody has been reported for use in flow cytometric analysis. Applications Tested: This HM-CCR5 (7A4) antibody has been tested by flow cytometric analysis of mouse thioglycolated- induced peritoneal exudate cells. This can be used at less than or equal to 0.25 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. PerCP-eFluor™ 710 can be used in place of PE-Cy5, PE-Cy5.5 or PerCP-Cy5.5. PerCP-eFluor™ 710 emits at 710 nm and is excited with the blue laser (488 nm). Please make sure that your instrument is capable of detecting this fluorochrome.

Human immunodeficiency virus (HIV) and related virus require coreceptors, in addition to CD4, to infect target cells. Some G protein-coupled receptors including CCR5, CXCR4, CCR3, CCR2b and CCR8 in the chemokine receptor family, and four new human molecules GPR15, STRL33, GPR1 and V28 were recently identified as HIV coreceptors. Among them, CCR5 (CC-CKR-5) is a principal coreceptor for macrophage- and dual-tropic HIV-1 strains fusion and entry of human white blood cells. CCR5 is required for the infection by HIV-1, HIV-2, and SIV. The beta-chemokines RANTES, MIP-alpha and MIP-beta are the ligands for CCR5 and prevent infection by M-tropic HIV-1. CCR5 associates with the surface CD4-gp120 of HIV complex and leads to membrane fusion and virus entry of target cells. The amino-terminal domain and the extracellular loops of CCR5 serve as HIV biding sites. CCR5 messenger RNA is expressed in lymphoid organs and monocytes.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

Can the eFluor Organic fluorochromes be used for intracellular staining?

Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).

What buffers are compatible with the eFluor Organic fluorochromes and eVolve QDots?

The eFluor Organic fluorochromes and eVolve QDots can be used with flow staining buffers containing PBS and protein.

What is the difference between eFluor Organic Dyes and eVolve Qdots?

The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
