MIP-1 beta (CCL4) human

产品说明

一般描述

Both MIP-1α and MIP-1β (macrophage inflammatory proteins-1α and β) are structurally and functionally related CC chemokines. They are secreted by activated human monocytes and peripheral blood lymphocytes. The gene encoding this protein is localized on human chromosome 17q12. Both human and murine MIP-1α and MIP-1β are active on human and murine hematopoietic cells. Recombinant human MIP-1β is a 7.6kDa protein containing 69 amino acid residues, including the four highly conserved cysteine residues present in CC chemokines.

生化/生理作用

MIP-1α and MIP-1β (macrophage inflammatory proteins-1α and β) 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 natural killer (NK) cells. While both MIP-1α and MIP-1β exert similar effects on monocytes their effect on lymphocytes differ; with MIP-1α selectively attracting CD8⁺ lymphocytes and MIP-1β (also known as C-C motif chemokine ligand 4) selectively attracting CD4⁺ lymphocytes. Additionally, MIP-1α and MIP-1β have also been shown to be potent chemoattractants for B cells, eosinophils and dendritic cells.

Lyophilized with no additives.

重悬

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8℃ for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20℃ to -80℃.
