Species: Human Expressing host: E. coli Description: Recombinant Human CCL3L1 Protein is produced byE. coliexpression system. The target protein is expressed with sequence (Ala24-Ala93) of human CCL3L1 (Accession #NP_001001437.2) fused with a 6His tag at the C-terminus. Tag: C-His Purity: > 95% by SDS-PAGE. Endotoxin: preparation: Lyophilized from a 0.22 m filtered solution of PBS, pH 7.4. Storage Store the lyophilized protein at -20C to -80C for 12 months.
After reconstitution, the protein solution is stable at -20C for 3 months, at 2-8C for up to 1 week.Unopened freeze-dried powder,Store at -20 to -80 °C for twelve months
Redissolution: Centrifge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.Redissolution:Store at -20 to -80 °C,avoid repeated freeze thaw cycles
Background Information : The two human MIP-1 alpha genes arise by duplication/mutation. They code for MIP-1 alpha isoforms CCL3/LD78 alpha and CCL3L1/LD78 beta, which share 94% amino acid (aa) sequence homology. Whereas the human CCL3/LD78 alpha is a single-copy gene, the human CCL3L1/LD78 beta gene copy number varies within the population. Human CCL3L1/LD78 beta cDNA encodes a 93 aa residue precursor with a 23 aa residue signal peptide that is cleaved to generate a 70 aa mature protein. Human CCL3L1/LD78 beta binds and signals through chemokine receptors CCR1 and CCR5. When compared to CCL3/LD78 alpha, CCL3L1/LD78 beta has higher binding affinity to CCR5, which also functions as a coreceptor for HIV-1 entry. The copy number of CCL3L1 is one of several genetic determinants of HIV-1 susceptibility (4).
