Bioyeargene Protein A ELISA Kit is intended for use in quantitating unnatural protein A constructs such as Recombinant Alkali-tolerant Protein A. The kit is for Research and Manufacturing Use Only and is not intended for diagnostic use in humans or animals. This kit is designed to provide a validated acidifing sample treatment method to dissociate Protein A from IgG products and detect Protein A contamination to less than 78pg/mL in the presence of up to 3mg/mL quantities of humanized monoclonal antibodies.

Principle of the Assayicon
Protein A ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for Protein A. Samples containing Protein A are first diluted in the Sample Diluent provided with the kits. The Denaturing Buffer is then added and mixed to dissociate the Protein A from the product antibody. The samples are then reacted in microtiter strips coated with a monoclonal anti-Protein A capture antibody. A second anti-Protein A biotinylated monoclonal antibody is simultaneously reacted forming a sandwich complex of solid phase antibody-Protein A:biotin labeled antibody. After a wash step to remove any unbound reactants, Streptavidin labeled HRP is added to each well. After a short incubation period, the strips are then reacted with TMB substrate. The enzyme-substrate reaction is terminated by addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Protein A concentration in each sample is interpolated from this standard curve.
Materials & Equipment Required But Not Providedicon
1. Precision pipettors and disposable tips to deliver 10-1000 μl. A multi-channel
pipette is desirable for large assays.
2. 100 mL and 1 liter graduated cylinders.
3. Distilled or deionized water.
4. Tubes to prepare sample dilutions.
5. Microplate reader capable of measuring absorbance at 450 nm.
6. Data analysis and graphing software.
