Stability of polypeptide immunoreactants and polyvinyl alcohol as a blocking agent on polyester cloth during dry storage.
During dry storage at 32 degrees C for 70 days, polypeptide immunoreactants (rabbit IgG and rabbit antiperoxidase antibody) adsorbed onto polyester cloth demonstrated no loss of immunoreactivity. Polyvinyl alcohol of molecular weight 30,000-70,000 provided a stable blocking capacity on the immunoreactant-adsorbed cloth without affecting immunoreactivity. Cloth-based enzyme immunoassay systems are suitable for field testing and transportation in the absence of refrigeration.
