ABSTRACT
Enzyme-linked immunosorbent assay (ELISA) is a sensitive immunoassay based on specific antigen-antibody reaction that is used for quantitative/qualitative analysis of various analytes in serum, plasma, saliva, cell and tissue lysates, and urine. ELISAs are typically performed in multi-well plates and depending on the design require coating antibody/antigen, analyte, detection antibodies, buffer, wash solution, and substrate/chromogen. Here we describe highly specific monoclonal antibody-based ELISA that detects circulating polymers formed by Pi*Z variant of human alpha-1-antitrypsin (Z-AAT). The circulating Z-AAT polymers are present in all individuals with inherited Pi*Z AAT deficiency. Thus, our assay provides a useful tool to examine the clinical significance and utility of Z-AAT polymers.
