title: Production of antibody for alpha 1-acid glycoprotein using carcinoembryonic antigen and normal fecal antigen.
abstract: The structural characteristics of carcinoembryonic antigen (CEA) and CEA-like antigen in feces and meconium were examined using antibody raised against 2 antigens. When antibody to CEA was made, anti-alpha 1-acid glycoprotein (AG) (nonprecipitating antibody) besides the precipitating antibody for CEA was made. When antibodies against each CEA-like antigen (mol. wt. 180,000) purified from feces and meconium were tested, each antibody showed a fused precipitin line for 2 antigens. Some antibodies showed the non-precipitating antibody for AG. CEA and CEA-like antigen in feces and meconium may be composed of 2 portions (AG portion and non-AG portion). Antibody specific to these antigens may be the antibody directed to the non-AG portion.
