Search criteria included “adrenergic receptor” for the Molecule Name, and each different species for which data was available (as determined from the list of hosts in the keyword search) from the Organism Finder. In the case of adrenergic receptor, though a total of 7 references were found, only 1 (PMID: 1378277) was specific to MG epitopes; the others were related to other autoimmune disease states. Listed in the table are the total numbers of epitopes (distinct molecular structure) and then distinct assays captured within the database. By definition this number does not indicate the number of individual epitopes, as each epitope is defined experimentally by one or more assays.
