Diagnosis of pregnancy in marmosets: hemagglutination inhibition test and radioimmunoassay for urinary chorionic gonadotropin. 1976

G D Hodgen, and L G Wolfe, and J D Ogden, and M R Adams, and C C Descalzi, and D F Hildebrand

The Subhuman Primate Pregnancy Test kit was used for diagnosis of pregnancy in 17 marmosets. This hemagglutination inhibition test for urinary chorionic gonadotropin accurately indicated conception by positive responses in 72 and 76 specimens collected between the 4th and 10th wk following the estimated time of fertilization. The rate of false positive results did not exceed 1%. A radioimmunoassay system was used to quantify chorionic gonadotropin concentrations in urine. Detectable levels were present by the 2nd week of pregnancy. Peak chorionic gonadotropin levels were found between the 7th to 9th wk after conception. Chorionic gonadotropin excretion rates declined to undetectable levels during the final month of gestation.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation. Radioimmunoassays
D002143 Callitrichinae A subfamily in the family CEBIDAE that consists of four genera: CALLITHRIX (marmosets), CALLIMICO (Goeldi's monkey), LEONTOPITHECUS (lion tamarins), and SAGUINUS (long-tusked tamarins). The members of this family inhabit the tropical forests of South and Central America. Cebuella,Genus Mico,Leontocebus,Mico Genus,Callithricidae,Callitrichidae,Cebuellas,Genus, Mico,Mico, Genus

D006063 Chorionic Gonadotropin A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).

D006385 Hemagglutination Inhibition Tests Serologic tests in which a known quantity of antigen is added to the serum prior to the addition of a red cell suspension. Reaction result is expressed as the smallest amount of antigen which causes complete inhibition of hemagglutination.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000882 Haplorhini A suborder of PRIMATES consisting of six families: CEBIDAE (some New World monkeys), ATELIDAE (some New World monkeys), CERCOPITHECIDAE (Old World monkeys), HYLOBATIDAE (gibbons and siamangs), CALLITRICHINAE (marmosets and tamarins), and HOMINIDAE (humans and great apes).
