Background

Macrophage Inflammatory Protein-4 (MIP-4) produced in E.Coli is a single, non-glycosylated polypeptide that attracts lymphocytes but not monocytes or granulocytes and is involved in B cell migration into B cell follicles in lymph nodes. It attracts naive T lymphocytes toward dendritic cells and activated macrophages in lymph nodes, has chemotactic activity for naive T cells, CD4+ and CD8+ T cells and thus may play a role in both humoral and cell-mediated immunity responses. MIP-4 is expressed at high levels in lung, lymph nodes, placenta, and bone marrow, not expressed by peripheral blood monocytes, and a monocyte-to-macrophage differentiation is a prerequisite for expression.

Protein Details

Purity
>97% by SDS-PAGE and analyzed by silver stain.
Endotoxin Level
<0.01 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Human MIP-4 was determined by by its ability to induce chemotaxis of resting T-lymphocytes and its ability to inhibit rhEotaxin induced chemotaxis on rat Y3 cells transfected with human CCR3 (Nibbs, RJB. et al., 2000, J. Immunol. 164:1488). The expected ED50 for these effects is typically 0.5 - 2 μg/ml and 1 - 5 μg/ml, respectively.
