This product is sold for research use only. Standard Laboratory Practices should be followed when handling this material.
Product contains sodium azide as a preservative. Although the amount of sodium azide is very small appropriate care must be taken when handling this product.
We recommend to avoid using bovine serum albumin (BSA) as a buffer component or blocking agent for SAA immunoassay. In buffers, BSA can be replaced with 1% casein.
Immunoassay plates blocking with casein is needed to prevent non-specific binding of SAA to the wells of an immunoassay plate.
For pairs SAA19cc – VSA34cc and SAA21cc – VSA34cc, we recommend to start assay optimization using 0.01% CHAPS in antigen dilution and washing buffers. According to our data, Tween 20 lowered the signal in the wells when it was used in concentration 0.05-0.1% in antigen dilution buffer.
When lower concentration of Tween 20 was used (0.005-0.025%), non-specific binding of SAA to the wells of an immunoassay plate was observed.
For pairs VSA2 – VSA38cc, VSA2 – VSA31cc and VSA38cc – VSA43, we recommend to use antigen dilution buffer containing 1% casein and 0.05-0.1% Tween 20.
