Pair SAA19cc – VSA34cc:
Plates blocking with casein is needed to prevent non-specific binding of SAA to the wells of an immunoassay plate. We recommend avoiding using bovine serum albumin (BSA) as a buffer component or blocking agent. In buffers, BSA can be replaced with 1% casein. According to our data, Tween 20 lowered the signal 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. Therefore, we recommend starting assay optimization using 0.01% CHAPS in antigen dilution and washing buffers. We recommend carrying out immunoassay at room temperature.
Pairs VSA2 – VSA38cc, VSA2 – VSA31cc, VSA38cc – VSA43, F571 – F173: Plates blocking with casein is needed to prevent non-specific binding of SAA to the wells of an immunoassay plate. For pairs VSA2 – VSA38cc, VSA2 – VSA31cc and VSA38cc – VSA43 we recommend avoiding using BSA as a buffer component or blocking agent. In buffers, BSA can be replaced with 1% casein. We recommend using antigen dilution buffer containing 0.05% Tween 20. We recommend carrying out immunoassay at 37 °C.
Pairs F227 – F529, F231 – F550, F240 – F501, F240 – F550: Plate blocking is not needed. We recommend using antigen dilution buffer containing 10 mg/ml BSA and 0.05% Tween 20. We recommend carrying out immunoassay at room temperature.
