Anti-RNP ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for Anti-RNP. Standards or samples are then added to the microtiter plate wells and Anti-RNP if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of Anti-RNP present in the sample, a standardized preparation of horseradish peroxidase (HRP) -conjugated polyclonal antibody, specific for Ant
