ABSTRACT:
A vessel containing a polymeric acid is used in a method and test kit for extracting a bacterial (e.g., streptococcal) antigen from a test sample, for example, preliminary to an immunoassay. To extract the antigen from bacteria in the sample, a precursor reagent is applied to the vessel acid and incubated with the sample. The kit includes a vial containing the acid and another vial containing the precursor. The kit is produced by including the acid polymer in the vial or vessel, e.g., as a pellet or coating.
