  • Specification
  • Recommended Products
  • Cat.No.
  • CSC-CTK0042
  • Description
  • MIP-1b is a member of the b (CC) family of chemokines. It is produced by fibroblasts, monocytes, T and B lymphocytes, neutrophils, smooth muscle cells, mast cells and tumor cell lines. MIP-1b is a chemoattractant for monocytes and T cells, preferentially CD4+. In addition, MIP-1b potentiates early hematopoietic precursors growth. MIP-1b binds to CCR1, CCR5 and US28 receptors. The recombinant protein encoding the mature polypeptide contains 69 amino acid residue and migrates with an apparent Mr of 7.8 kDa.
  • Species
  • Mouse
  • Product Overview
  • Mouse Ccl4 expressed in E.coli
  • Sequence
  • A DNA sequence encoding the mature mouse MIP-1b protein was expressed in E. coli.
  • Size
  • CAT# CSC-CTK0042-10 (10 μg); CAT# CSC-CTK0042-50 (50 μg)
  • Expression System
  • E.coli
  • Purity
  • Greater than 97% as determined by SDS-PAGE and visualized by silver stain
  • Activity
  • Activity was determined by ability to chemoattract mouse BaF/3 cells transfected with hCCR5 and the ED50 for this effect was typically 3 - 12 ng/mL.
  • Endotoxin Level
  • Endotoxin level less than 0.1 ng per 1 μg of the cytokine as determined by the LAL method.
  • Formulation
  • Lyophilized from a 0.2 μm filtered solution in 30% acetonitrile, 0.1% TFA containing 50 μg of bovine serum albumin per 1 μg of cytokine.
  • Reconstitution
  • It is recommended that sterile phosphate-buffered saline containing at least 0.1% human serum albumin or bovine serum albumin be added to the vial to prepare a stock solution of no less than 10 μg/mL of the cytokine.
  • Storage & Stability
  • Lyophilized samples are stable for greater than six months at -20°C to -70°C. Reconstituted mouse MIP-1b/CCL4 can be stored under sterile conditions at 2°C to 4°C for one month or at -20°C to -70°C for three months without detectable loss of activity. Avoid repeated freeze-thaw cycles.
