Active Recombinant Human CCL4 Protein (Ala24-Asn92), Animal-free, Carrier-free

• Cat.No.: CCL4-269H
• Product Overview: Recombinant Human CCL4 Protein (Ala24-Asn92) without tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: C-C Motif Chemokine Ligand 4 (CCL4) is a 7.66 kDa cytokine with 69 amino acid residues. CCL4, also named macrophage inflammatory protein-1β (MIP-1β), is mainly secreted from neutrophils, monocytes, B cells, T cells, fibroblasts, endothelial cells and epithelial cells. CCL4 recruits various immune cells like natural killer cells, monocytes, and neutrophils when CCL4 binds to CCR5. In addition, CCL4 mediates lymphocyte adhesion by Rac1 /Cdc42 signaling pathway and plays critical roles in different biological functions like maintenance of cell polarity, regulation of calcium ion transport and response to viruses.
• Source: E. coli
• Species: Human
• Tag: Tag Free
• Form: Lyophilized
• Bio-activity: Measure by its ability to chemoattract BaF3 cells transfected with human CCR5. The ED50 for this effect is < 10 ng/mL.
• Molecular Mass: The protein has a calculated MW of 7.75 kDa.
  The protein migrates as 11 kDa under reducing condition (SDS-PAGE analysis).
• Protein Length: Ala24-Asn92
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >98% as determined by SDS-PAGE analysis.
• Storage: This product is stable after storage at:
  -20 centigrade for 12 months in lyophilized state from date of receipt.
  -20 or -80 centigrade for 1 month under sterile conditions after reconstitution.
  Avoid repeated freeze/thaw cycles.
• Storage Buffer: Lyophilized from a 0.2 μm filtered solution containing 50 mM Tris and 150 mM NaCl, pH 8.5.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
• Shipping: The product is shipped with polar packs. Upon receipt, store it immediately at -20 centigrade or lower for long term storage.
