特异性

Clone 2L2 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects human C-X-C chemokine receptor 4 (CXCR4). It targets an epitope within 12 amino acids from the N-terminal region.

免疫原

KLH-conjugated linear peptide corresponding to 12 amino acids from the N-terminal region of human C-X-C chemokine receptor type 4 (CXCR4).

应用

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected CXCR4 in human adrenal gland tissue sections.
ELISA Analysis: A representative lot specifically detected CXCR4 peptide in ELISA application, but not peptides from five other proteins.
Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected CXCR4 in Jurkat and K562 cell lines.
Affinity Binding Assay: A representative lot of this antibody bound CXCR4 with a KD of 3.6 x 10-10 in an affinity binding assay.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.
Anti-CXCR4, clone 2L2 ZooMAb, Cat. No. ZRB1357, a recombinant Rabbit monoclonal antibody that targets human CXCR4 and is tested in Affinity Binding Assay, ELISA, Immunocytochemistry, and Immunohistochemistry (Paraffin).

目标描述

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 receptor for the C-X-C chemokine CXCL12/SDF-1 that transduces a 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 serine 325 leads to recruitment of ITCH (E3 ubiquitin-protein ligase), ubiquitination and protein 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. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
