title: Evaluation of protein A and protein G as indicator system in an ELISA for detecting antibodies in mink to Pseudomonas aeruginosa.
abstract: A modified, indirect enzyme-linked immunosorbent assay (ELISA) was developed and applied in the detection of mink antibodies to Pseudomonas aeruginosa. In this assay, peroxidase conjugated protein A and protein G were evaluated as indicator systems for detecting antigen-antibody complexes. It was found that protein A has a strong affinity for mink immunoglobulins. In contrast, protein G showed no such affinity. The affinity of protein A for mink immunoglobulins was further demonstrated by immunoprecipitation assays.
