货号 | AF799-SP |
别名 | MIPI; MIP-I | 全称 | Macrophage Inflammatory Protein I |
应用 | Western Blot(0.1 µg/mL) |
目标/特异性 | Detects viral MIP‑I in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 2% cross‑reactivity with recombinant viral MIP-II is observed. |
使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize MIP‑I-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR8. The Neutralization Dose (ND50) is typically 0.8-4.0 µg/mL in the presence of 0.02 µg/mL Recombinant Viral MIP‑I. |

背景 | Human herpesvirus-8 (HHV-8)/Kaposi’s sarcoma-associated herpesvirus (KSHV) encodes a variety of immunomodulatory proteins which were apparently pirated from cellular genes by the virus. Three chemokine-like proteins, vMIP-I, vMIP-II and vMIP-III have been found within the HHV-8 genome. Viral MIP-II cDNA encodes a 94 amino acid (aa) residue precursor protein with a 23 aa residue signal peptide that is cleaved to yield a 71 aa residue mature protein. Among human chemokines, vMIP-II is most closely related to MIP-1 alpha, sharing approximately 41% amino acid sequence identity. At the amino acid sequence level, vMIP-I and vMIP-II also share 48% identity. |

Chemotaxis Induced by MIP‑I and Neutralization by Viral MIP‑I Antibody. Recombinant Viral MIP‑I (Catalog # 600‑VA) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CCR8 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 Recombinan Viral MIP‑I (0.02 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Viral MIP-I Antigen Affinity-purified Polyclonal Antibody (Catalog # AF799). The ND50 is typically 0.8‑4.0 µg/mL. |
