Scientific Data Images for Human CXCL5/ENA-78 Antibody

CXCL5/ENA-78 in Human Colon Cancer Tissue.

CXCL5/ENA-78 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using Mouse Anti-Human CXCL5/ENA-78 Monoclonal Antibody (Catalog # MAB254) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in epithelial cells and secreted protein. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.
Chemotaxis Induced by CXCL5/ENA‑78 and Neutral-ization by Human CXCL5/ENA‑78 Antibody.

Chemotaxis Induced by CXCL5/ENA‑78 and Neutral-ization by Human CXCL5/ENA‑78 Antibody.

Recombinant Human CXCL5/ENA-78 (Catalog # 254-XB) chemoattracts the BaF3 mouse pro-B cell line transfected with human CXCR2 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human CXCL5/ENA-78 (0.03 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CXCL5/ENA-78 Monoclonal Antibody (Catalog # MAB254). The ND50is typically 3-15 µg/mL.

Applications for Human CXCL5/ENA-78 Antibody

Background: CXCL5/ENA-78

CXCL5, also known as epithelial cell-derived-neutrophil-activating-peptide (ENA78), is an 8 kDa proinflammatory member of the CXC subfamily of chemokines. Its Glu-Leu-Arg (ELR) motif confers angiogenic properties and distinguishes it from ELR- CXC chemokines which are angiostatic. Human CXCL5 shares 57% amino acid (aa) sequence identity with mouse and rat CXCL5. Among other human ELR+ chemokines, it shares 77% aa sequence identity with CXCL6/GCP2 and 35%‑51% with CXCL1/GRO alpha, CXCL2/GRO beta, CXCL3/GRO gamma, CXCL7/NAP2, and CXCL8/IL8. Inflammatory stimulation upregulates CXCL5 production in multiple hematopoietic cell types, fibroblasts, endothelial cells, and vascular smooth muscle cells. In vivo, CXCL5 is elevated at sites of inflammation and pulmonary fibrosis where it promotes neutrophil infiltration and activation as well as angiogenesis. Its upregulation contributes to increased vascularization, tumor growth, and metastasis in many cancers. Full length CXCL5 (78 aa) is trimmed at the N-terminal end by Cathepsin G and chymotrypsin to ENA74 (74 aa) and ENA70 (70 aa), with the shortened forms showing increased potency relative to full length CXCL5. CXCL5 exerts its effects primarily through interactions with CXCR2. It also binds DARC, a decoy chemokine receptor which can limit CXCR2-mediated responses.
