Species: Human Expressing host: E. coli Description: Active Recombinant Human CCL2/MCP-1 Protein is produced byE. coliexpression system. The target protein is expressed with sequence (Gln24-Thr99) of human CCL2/MCP-1 (Accession #NP_002973.1) fused with no additional amino acid. Tag: No tag Purity: > 90% by SDS-PAGE. Endotoxin: Biological Activity: 1.Measured by the ability to inhibit the proliferation of HUVEC(Human Umbilical Vein Endothelial Cells).The ED50for this effect is 0.53-2.12 ng/mL.
2.Measured by its ability to chemoattract THP-1 cells. The ED50for this effect is typically 1.01-4.04 ng/mL. preparation: Lyophilized from a 0.22 m filtered solution of PBS, pH 7.4. Storage Store the lyophilized protein at -20C to -80C for long term.
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: Centrifuge 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:后的蛋白溶液按照需求进行分装Storage于-20C至-80C随取随用避免反复冻
Background Information : Monocyte chemoattractant protein 1 (MCP-1), also called CCL2, belongs to a group of CC chemokines located in chromosome 17q11.2. MCP-1 protein interacts with chemokine C-C motif receptor 2 (CCR2) to activate and recruit monocytes, macrophages, CD4+ T cells and immature dendritic cells to the site of infection. The presence of MCP-1 protein in an adequate concentration is important for granuloma formation and M. tuberculosis clearance. GeneID 6347 Swiss Prot P13500 Alias: CCL2;GDCF-2;HC11;HSMCR30;MCAF;MCP-1;MCP1;SCYA2;SMC-CFMedChemExpress (MCE) recombinant proteins include: cytokines, enzymes, growth factors, hormones, receptors, transcription factors, antibody fragments, etc. They are often essential for supporting cell growth, stimulating cell signaling pathways, triggering or inhibiting cell differentiation; and are useful tools for elucidating protein structure and function, understanding disease onset and progression, and validating pharmaceutical targets. At MedChemExpress (MCE), we strive to provide products with only the highest quality. Protein identity, purity and biological activity are assured by our robust quality control and assurance procedures.
