| 反应种属 | Rat |
| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects rat CCL20/MIP-3 alpha in direct ELISAs and Western blots. In these formats, approximately 50% cross-reactivity with recombinant human CCL20/MIP-3 alpha is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize CCL20/MIP‑3 alpha -induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR6. The Neutralization Dose (ND50) is typically 30-75 µg/mL in the presence of 5 µg/mL Recombinant Rat CCL20/MIP‑3 alpha. |

| 背景 | CCL20, also known as MIP-3 alpha, LARC (Liver and Activation-regulated Chemokine) and as Exodus, is one of many novel beta chemokines identified through bioinformatics. Rat CCL20 cDNA encodes a 96 amino acid (aa) precursor protein with a 25 aa putative signal peptide that is predicted to be cleaved to form the 71 aa mature secreted protein. CCL20 is distantly related to other beta chemokines (20-28% aa sequence identity). Rat MIP-3 alpha shares approximately 70 and 61% aa sequence homology with mouse and human CCL20, respectively. CCL20 has been shown to be expressed predominantly in lymph nodes, appendix, PBL, fetal liver, fetal lung, and epithelial cells of intestinal tissues. The expression of CCL20 is strongly up-regulated by inflammatory signals and down-regulated by the anti-inflammatory cytokine IL-10. Synthetic or recombinant CCL20 has been shown to be chemotactic for lymphocytes and dendritic cells, and inhibits proliferation of myeloid progenitors in colony formation assays. CCL20 has now been shown to be a unique functional ligand for CCR-6 (previously referred to as GPR-CY4, CKR-L3, or STRL22 orphan receptor), a chemokine receptor that is selectively and highly expressed in human dendritic cells derived from CD34+ cord blood precursors. |

Chemotaxis Induced by CCL20/MIP‑3 alpha and Neutralization by Rat CCL20/MIP‑3 alpha Antibody. Recombinant Rat CCL20/MIP‑3 alpha (Catalog # 540-RM) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CCR6 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 Rat CCL20/MIP‑3 alpha (5 µg/mL) is neutralized (green line) by increasing concentrations of Rat CCL20/MIP‑3 alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF540). The ND50 is typically 30-75 µg/mL. |
