Species: Human Expressing host: E. coli Description: Recombinant Human CCL23/Ck beta 8-1 Protein is produced byE. coliexpression system. The target protein is expressed with sequence (Arg22-Asn120) of human CCL23/Ck beta 8-1 (Accession #P55773) fused with no additional amino acid. Tag: No tag Purity: > 95% by SDS-PAGE. Endotoxin: preparation: Lyophilized from a 0.2 m filtered solution of 20 mM PB, 250 mM NaCl, pH 7.2. Storage Store the lyophilized protein at -20C to -80 C for long term.
After reconstitution, the protein solution is stable at -20 C for 3 months, at 2-8 C 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:Store at -20 to -80 °C,avoid repeated freeze thaw cycles
Background Information : Chemokines form a superfamily of secreted proteins involved in immunoregulatory and inflammatory processes. The superfamily is divided into four subfamilies based on the arrangement of the N-terminal cysteine residues of the mature peptide. This chemokine, a member of the CC subfamily, displays chemotactic activity on resting T lymphocytes and monocytes, lower activity on neutrophils and no activity on activated T lymphocytes. The protein is also a strong suppressor of colony formation by a multipotential hematopoietic progenitor cell line. In addition, the product of This protein is a potent agonist of the chemokine (C-C motif) receptor 1. Alternative splicing results in multiple transcript variants that encode different isoforms. GeneID 6368 Swiss Prot P55773-1 Alias: CCL23;CK-BETA-8;CKb8;Ckb-8;Ckb-8-1;MIP-3;MIP3;MPIF-1;SCYA23;hmrp-2aMedChemExpress (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.
