Title: The antigens of pigeon breeder's disease. III. Immunologically related antigens of pigeon dropping extracts: PDE1,2,A and B. Author: Fredricks WW, Tebo TH. Journal: Int Arch Allergy Appl Immunol; 1980; 61(1):65-74. PubMed ID: 6153077. Abstract: Antigen PDEB was purified from pigeon dropping extracts and characterized as a basic glycoprotein, containing 93% protein and 7% carbohydrate, with a molecular weight of approximately 51,000. Based on its size, subunit composition, and cross-reactions with PDE1 (pigeon IgA) and papain digestion products of PDE1, PDEB appears to be the basic Fab fragments of antigen PDE1. The acidic Fab fragments (PDEA) and the Fc fragments (PDE2) of PDE1 were also isolated from the whole PDE as 50,000 MW components.[Abstract] [Full Text] [Related] [New Search]
