Recombinant Mouse CCL4/MIP-1 beta Protein

Description :
FAQ COA 已发表文献 Both MIP-1 and MIP-1 are structurally and functionally related CC chemokines. They participate in host response to invading bacterial, viral, parasite and fungal pathogens by regulating the trafficking and activation state of selected subgroups of inflammatory cells (.g. macrophages, lymphocytes and NK cells). While both MIP-1 and MIP-1 exert similar effects on monocytes, their effect on lymphocytes differ; with MIP-1 selectively attracting CD8+ lymphocytes, and MIP-1 selectively attracting CD4+ lymphocytes. Additionally, MIP-1 and MIP-1 have also been shown to be potent chemoattractants for B cells, eosinophils and dendritic cells. Both human and murine MIP-1 and MIP-1 are active on human and murine hematopoietic cells. Recombinant MouseMIP-1 is a 7.8 kDa protein containing 69 amino acid residues, including the four highly conserved cysteine residues present in CC chemokines.

The biological activity determined by a chemotaxis bioassay using human monocytes is in a concentration range of 20-100 ng/mL. Endotoxin EU/g of proteinas determined by LAL method. Formulation Lyophilized from a 0.2 m filtered concentrated solution in 2PBS, pH 7.4. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at -20C. Further dilutions should be made in appropriate buffered solutions.
