Two pancreas "tissue-specific" antigens in normal human urine, one being and esterase. 1975

E L Greene, and S P Halbert, and D Kiefer

Hyperimmune antiserum to human pancreas was exhaustively absorbed with plasma, kidney, and submaxillary gland. The resulting antiserum showed up to seven antigens in pancreas extracts by gel diffusion methods, but failed to react detectably with extracts of 17 other organs and tissues. However, this apparently "tissue-specific" anti-pancreas reagent regularly revealed two of the pancreas antigens in normal human urine concentrates. One of the latter was an anodal esterase. Although the identity of the second is not yet known, it was shown to be devoid of the following enzyme activities: amylase, catalase, glucosaminidase, glucuronidase, cystine-aminopeptidase, phosphatases and sulfatase.

UI MeSH Term Description Entries
D007106 Immune Sera Serum that contains antibodies. It is obtained from an animal that has been immunized either by ANTIGEN injection or infection with microorganisms containing the antigen. Antisera,Immune Serums,Sera, Immune,Serums, Immune
D007118 Immunoassay A technique using antibodies for identifying or quantifying a substance. Usually the substance being studied serves as antigen both in antibody production and in measurement of antibody by the test substance. Immunochromatographic Assay,Assay, Immunochromatographic,Assays, Immunochromatographic,Immunoassays,Immunochromatographic Assays
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D008297 Male Males
D009280 Naphthaleneacetic Acids Naphthalene derivatives containing the -CH2CCO2H radical at the 1-position, the 2-position, or both. Compounds are used as plant growth regulators to delay sprouting, exert weed control, thin fruit, etc. Acids, Naphthaleneacetic
D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D010184 Pancreatic Extracts Extracts prepared from pancreatic tissue that may contain the pancreatic enzymes or other specific uncharacterized factors or proteins with specific activities. PANCREATIN is a specific extract containing digestive enzymes and used to treat pancreatic insufficiency.

D004950 Esterases Any member of the class of enzymes that catalyze the cleavage of an ester bond and result in the addition of water to the resulting molecules. Esterase
