Description:
Recombinant SAA consists of 121 amino acids and has a predicted molecular mass of 13766 kDa. Consists of a polypeptide corresponding to 1-111 a.a.r. of canine SAA and a proprietary 10 a.a.r. affinity tag on the N-terminus.
-
Applications:
Can be used as a control in immunoassays.

Other information:
Avoid repeated freezing and thawing. It is recommended to aliquot the product after reconstitution. To prepare diluted samples of SAA it is recommended to use buffer solutions containing a detergent. The selection of an appropriate detergent and its concentration is essential for the assay performance. For sandwich immunoassays using monoclonal anti-SAA antibodies SAA19, SAA21 and VSA34 we recommend using 0.01% CHAPS in antigen dilution buffer (e.g. 0.05 M Tris-HCl, pH 8.0, 0.15 M NaCl, 0.01 % CHAPS). For sandwich immunoassays using monoclonal anti-SAA antibodies VSA6, VSA25, VSA31, VSA38, VSA2, and VSA43 we recommend using 0.05 % Tween 20 in antigen dilution buffer (e.g. 0.02 M Tris-HCl, pH 7.5, 0.15 M NaCl, 0.05 % Tween 20).
