MIP-3β is a CC chemokine, expressed in the thymus, lymph nodes, and in activated bone marrow stromal cells that signals through the CCR7 receptor. MIP-3β is a chemoattractant for T and B lymphocytes, and myeloid progenitor cells. Human MIP-3β is active on murine cells. Recombinant Murine MIP-3β is a 9.2 kDa protein containing 83 amino acid residues, including the four highly conserved cysteine residues present in CC chemokines.

≥ 98% by SDS-PAGE gel and HPLC analyses.
Determined by its ability to chemoattract activated human T cells expressing the CCR7 receptor. The ED50 for this effect is 30-90 ng/ml.
Calculated Molecular Weight:
Endotoxin level is < 0.1 ng/ug of protein (< 1 EU/ug)
Not for human use.
