- Description
| Specificity Profile | More Information |
 | The specificity of CXCR4 Monoclonal Antibody (CSB0044) was tested on the Membrane Proteome Array™ and shown to be specific for human CXCR4. The Membrane Proteome Array™ contains 6,000 different human membrane proteins, each expressed in unfixed avian cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array™ represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |

CXCR4 is a multi-pass transmembrane protein and CXC chemokine receptor. CXCR4 is involved in a variety of biological processes as a receptor for stromal cell-derived factor-1, ubiquitin, bacterial lipopolysaccharide and a coreceptor for HIV-1. CXCR4 is also associated with breast cancer and WHIM syndrome. (NCBI Gene: 7852, UniProtKB/Swiss-Prot: P61073).
