Class-specific anti-IgA antibodies occurred in 0.8% of non-IgA-deficient sera and 24.3% of IgA-deficient sera. Antibodies reacting with IgA1 only occurred in 2.6% of non-IgA-deficient sera and 6.7% of IgA-deficient sera. Antibodies reacting with IgA2 only occurred in 0.6% of non-IgA-deficient sera and 2.7% of IgA-deficient sera. The prevalence of anti-IgA in IgA deficients with inflammatory disease was higher (81.8%) than in IgA deficients without disease (24.1 %) and was accounted for by class-specific antibodies.<\/jats:p>","DOI":"10.1159\/000234078","type":"journal-article","created":{"date-parts":[[2009,8,5]],"date-time":"2009-08-05T05:41:56Z","timestamp":1249450916000},"page":"337-341","source":"Crossref","is-referenced-by-count":9,"title":["IgG Anti-IgA1 and Anti-IgA2 Antibodies: Their Measurement by an Enzyme-Linked Immunosorbent Assay and Their Relationship to Disease"],"prefix":"10.1159","author":[{"given":"R.E.","family":"Petty","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.D.","family":"Sherry","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.M.","family":"Johannson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,8,5]]},"container-title":["International Archives of Allergy and Applied Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/234078","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000234078","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T10:48:09Z","timestamp":1777632489000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000234078"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,8,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000234078","archive":["Portico"],"relation":{},"ISSN":["0020-5915","2571-6662"],"issn-type":[{"value":"0020-5915","type":"print"},{"value":"2571-6662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,8,5]]}}}
