Recombinant Human MIP-1 beta/CCL4

Both MIP-1alpha and MIP-1beta are structurally and functionally related CC chemokines. They participate in the host response to invading bacterial, viral, parasite and fungal pathogens by regulating the trafficking and activation state of selected subgroups of inflammatory cells e.g. macrophages, lymphocytes and NK cells. While both MIP-1alpha and MIP-1beta exert similar effects on monocytes their effect on lymphocytes differ, with MIP-1alpha selectively attracting CD8+ lymphocytes and MIP-1beta selectively attracting CD4+ lymphocytes. Additionally, MIP-1alpha and MIP-1beta have also been shown to be potent chemoattractants for B cells, eosinophils and dendritic cells. Both human and mouse MIP-1alpha and MIP-1beta are active on human and mouse hematopoietic cells.

Lyophilized from a 0.2 um filtered concentrated solution in 20 mM Tris + 500 mM NaCl.

Centrifuge vial prior to opening. Add sterile distilled water or aqueous buffer to a concentration of 0.1-1.0 mg/mL. Further dilutions should be made in appropriate buffered solutions.
