Cat#:RP-2395H;Product Name:Recombinant Human CCL28 Protein;Synonym:MEC, CCK1, SCYA28, MGC71902, CCL28, C-C motif chemokine 28, Small-inducible cytokine A28, Mucosae-associated epithelial chemokine, Protein CCK1.;Description:CCL28 Protein produced in E.coli is a single, non-glycosylated, polypeptide chain containing 108 amino acids and having a molecular mass of 12.3 kDa. The CCL28 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:SEAILPIASS CCTEVSHHIS RRLLERVNMC RIQRADGDCD LAAVILHVKR RRICVSPHNH TVKQWMKVQA AKKNGKGNVC HRKKHHGKRN SNRAHQGKHE TYGHKTPY.;Purity:Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:Determined by its ability to chemoattract human lymphocytes using a concentration range of 1-10ng/ml corresponding to a Specific Activity of 100,000-1,000,000IU/mg.;Formulation:Lyophilized from a concentrated (1mg/ml) solution in water containing 20mM PBS and 150mM NaCl.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized CCL28 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized CCL28 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CCL28 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
