In response to discussions at the 16th International Histocompatibility and Immunogenetics Workshop, members of the Johns Hopkins Immunogenetics Laboratory have created a website for all things related to solid phase antibody immunoassays. At www.immunoassays.net, you can enter into discussions about test interpretation and troubleshooting. The site provides information on the latest assays, performance of different test lots, correlations between solid phase and cell based test results, and serum treatments. There is information on bead assays, flow cytometry and ELISA as well as links to relevant publications. Please visit the website and become a member at www.immunoassays.net. You can become a site moderator and lead discussions.
