Cat#:RP-5592H;Product Name:Recombinant Human SAA1 Protein;Synonym:Serum amyloid A protein, SAA, Amyloid protein A, Amyloid fibril protein AA, SAA1, SAA2, PIG4, TP53I4, MGC111216.;Description:SAA1 Protein produced in E.coli is a single, non-glycosylated polypeptide chain containing 104 amino acids and having a molecular mass of 11.7kDa. The SAA1 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:RSFFSFLGEA FDGARDMWRA YSDMREANYI GSDKYFHARG NYDAAKRGPG GVWAAEAISD ARENIQRFFG HGAEDSLADQ AANEWGRSGK DPNHFRPAGL PEKY.;Purity:Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:The biological activity determined by a chemoattract bioassay using human monocytes is in a concentration range of 10-100 ng/ml.;Formulation:SAA1 was lyophilized from a 0.2µm filtered concentrated solution in 20mM Tris-HCl, pH 8.5 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 SAA1 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized SAA1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution SAA1 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.;
