别名 | LIX |
反应种属 | Mouse |
应用 | Western Blot(0.1 µg/mL) |
目标/特异性 | Detects mouse LIX in direct ELISAs and Western blots. In direct ELISAs, less than 5% cross-reactivity with recombinant human GCP‑2, recombinant rat (rr) CINC‑2 alpha, rrCINC-2 beta, recombinant mouse (rm) KC, and rmMIP‑2 is observed. |
使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize LIX-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR2. The Neutralization Dose (ND50) is typically 1-5 µg/mL in the presence of 0.2 µg/mL Recombinant Mouse LIX. |

背景 | LIX ( Liposaccharide-Induced CXC chemokine; also GARG-8 and Cxcl5) is a secreted 8-9 kDa member of the Intercrine alpha (or CxC) family of chemokines. It is widely expressed, being produced by diverse cell types such as fibroblasts, thymic epithelium, platelets, vascular endothelium, hepatocytes, lung type II alveolar cells and ileal columnar epithelium. As a chemokine, LIX demonstrates chemokinetic properties. It induces the chemotaxis of neutrophils and endothelial cells, and also promotes TNF-alpha secretion from mast cells and macrophages. Notably, circulating LIX is not derived from fibroblasts, but platelets. This suggests that neutrophil homeostasis/chemotaxis is a function of local resident cell activation and LIX secretion, not generally circulating LIX. Mouse LIX is synthesized as a 132 amino acid (aa) precursor that contains a 40 aa signal sequence, a 78 aa mature region (aa 41-118), and a cleavable 14 aa C-terminus. The mature region possesses an ELR/GluLeuArg motif between aa 50-52, and an alpha -family characteristic CxC motif between aa 53-55. Although there are no known splice variants of mouse LIX, considerable proteolytic processing occurs at both the N- and C-termini over aa 41-132. This may reduce the MW in SDS-PAGE by as much as 3 kDa. The majority of LIX appears to start between aa 47-50, and this is positively correlated with bioactivity. Over aa 41-118, mouse LIX shares 73% aa sequence identity with rat LIX. Although not a strict ortholog, mouse LIX shares 63% aa sequence identity with human GCP-2. |

Chemotaxis Induced by LIX and Neutralization by Mouse LIX Antibody. Recombinant Mouse LIX (Catalog # 433-MC) 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 Mouse LIX (0.2 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse LIX Antigen Affinity-purified Polyclonal Antibody (Catalog # AF433). The ND50 is typically 1‑5 µg/mL. |
