ANTI-HUMAN CXCR4/CD184 (12G5) COLORWHEEL DYE-READY MAB

General description

ColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^® antibody with any ColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^® antibody and dye is lyophilized for long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^® technology requires both ColorWheel^® antibody and ColorWheel^® dye for Flow Cytometry application.

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Green Chemistry.This product is Preservative-free, lyophilized product for enhanced stability and allow for ambient shipping and thus aligns with "Waste Prevention", "Designing Safer Chemicals" and "Design for Energy Efficiency".

Target description

C-X-C chemokine receptor type 4 (UniProt: P61073; also known as CXC-R4, CXCR-4, FB22, Fusin, HM89, LCR1, Leukocyte-derived seven transmembrane domain receptor, LESTR, Lipopolysaccharide-associated protein 3, LAP-3, LPS-associated protein 3, NPYRL, Stromal cell-derived factor 1 receptor, SDF-1 receptor, CD184) is encoded by the CXCR4 gene (Gene ID: 7852) in human. CXCR-4 is a multi-pass membrane protein with four extracellular domains, seven transmembrane domains, and four cytoplasmic domains. It serves as a receptor for the C-X-C chemokine CXCL12/SDF-1 and transduces signal by increasing intracellular calcium levels and enhancing MAPK1/MAPK3 activation. CXCR-4 is expressed in numerous tissues and two isoforms have been reported that are generated by alternative splicing. Isoform 1 is the predominant form in all tissues tested. CXCR-4 is rapidly phosphorylated on serine and threonine residues in the C-terminal region upon agonist stimulation. Phosphorylation at serine 324 and 325 leads to the recruitment of ITCH (E3 ubiquitin-protein ligase) that leads to its ubiquitination and degradation. Sulfation on tyrosine 21 is shown to be essential for efficient binding of CXCL12/SDF-1alpha and it promotes its dimerization. Tyrosine 7 and tyrosine 12 are sulfated in a sequential manner following complete sulfation of tyrosine 21. CXCR-4 acts as a co-receptor for human HIV-1 virus isolates (CD4 being the primary receptor) and as a primary receptor for HIV-2 isolates. CXCR-4 can also bind bacterial lipopolysaccharide (LPS) and mediate LPS-induced inflammatory response, including TNF-alpha secretion by monocytes. CXCR-4 is reported to be essential for metastatic spread to organs where CXCL12 is expressed, which allows tumor cells to access cellular niches that favor tumor-cell survival and growth. Mutations in CXCR4 gene are reported to cause WHIM syndrome that is characterized by neutropenia, hypogammaglobulinemia and extensive human papillomavirus (HPV) infection.
