• Storage Conditions: The lyophilized Apo-SAA recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted Apo-SAA is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing Apo-SAA recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Additional Information:

Human apo-SAA is a 104 amino acid polypeptide that circulates primarily in association with high-density lipoproteins (HDL). The level of apo-SAA, normally 1-5 and#956;g/mL in plasma, increases 500-1000 fold within 24 hours of an inflammatory stimulus and, under these conditions, is the most abundant HDL apo-lipoprotein. The human SAA gene codes for a 122 amino acid polypeptide, which contains an 18 amino acid N-terminal signal sequence. Recombinant Apo-SAA is a consensus SAA molecule corresponding to human apo-SAA1alpha except for the presence of an N-terminal methionine and substitution of asparagine for aspartic acid at position 60 and arginine for histidine at position 71(the later two substituted residues are present in apo-SAA2beta).
