Product Name: Serum Amyloid A (APO-SAA) Human Recombinant Synonyms: Description: APO-SAA Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 104 amino acids and having a molecular mass of 11.7kDa. Recombinant Apo-SAA is a consensus SAA molecule corresponding to human Apo-SAA1a, except for the presence of an N-terminal methionine, the substitution of asparagine for aspartic acid at position 60, and arginine for histidine at position 71 (the latter two substituted residues are present in Apo-SAA2b).The Human APO-SAA is purified by proprietary chromatographic techniques. Uniprot Accesion Number: Amino Acid Sequence:RSFFSFLGEA FDGARDMWRA YSDMREANYI GSDKYFHARG NYDAAKRGPG GVWAAEAISN ARENIQRFFG RGAEDSLADQ AANEWGRSGK DPNHFRPAGL PEKY. Source: Escherichia Coli. Physical Appearance and Stability: Lyophilized Human SAA although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution Human SAA should be stored at 4C between 2-7 days and for future use below -18C.Please prevent freeze-thaw cycles. Formulation and Purity: Human SAA was lyophilized from a concentrated (1mg/ml) solution in 20mM Tris-HCl, pH 9.0 and 150mM NaCl. Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. Application: Solubility: It is recommended to reconstitute the lyophilized SAA Human in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: The biological activity determined by its ability to down-regulate lipid biosynthesis in aortic smooth muscle cells. The effective concentration was found to be 4uM. Shipping Format and Condition: Lyophilized powder at room temperature. Usage Statement: Our products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
