Fetal Diagnosis and Therapy, 1993
The addition of maternal serum intact hCG (MShCG) to routine maternal serum alpha-fetoprotein screening for Down's syndrome is expected to yield a detection efficiency around 60% for an amniocentesis rate approximating 5%. We compared the detection rate using intact MShCG and free-beta hCG in 480 normal pregnancies and 48 with chromosome defects (Down ...

ABSENCE OF THE COOH-TERMINAL PEPTIDE ON ECTOPIC HUMAN CHORIONIC GONADOTROPIN B-SUBUNIT (hCGB)
Endocrinology, 1982A comparison of the physical properties and immunoreactivity of ectopic hCG beta from cultured cervical cancer cells and standard hCG beta was performed. The heterogeneity of the preparations was examined by ion-exchange chromatography, and the molecular size by analytical gel filtration. Two distinct forms of ectopic hCG beta were identified. One form

Location of major antigenic sites of the β-subunit of human chorionic gonadotropin
Biochemistry, 1978Purified beta subunit of human chorionic gonadotropin (hCG) was partially reduced with beta-mercaptoethanol, carboxymethylated, and digested with chymotrypsin. The peptides were isolated by high-voltage electrophoresis and paper chromatography. Five major disulfide-containing peptides were isolated, and their location in the parent molecule was ...

A nicked beta-subunit of human chorionic gonadotropin purified from pregnancy urine.
Journal of biochemistry, 1990Human chorionic gonadotropin (hCG) is a glycoprotein hormone composed of two dissimilar subunits (alpha and beta) and normally excreted in urine of pregnant women. An uncommon beta-subunit of hCG was purified from fresh early normal pregnancy urine by Sepralyte C8, resin adsorption. Sephadex G-100 column chromatography, and reverse-phase HPLC. SDS-PAGE

Human chorionic gonadotropin (beta-subunit) in the early diagnosis of ectopic pregnancy.
Obstetrics and gynecology, 1978In 15 women with suspected ectopic pregnancy considerable amounts of beta-subunit of human chorionic gonadotropin (hCG) were detected in the serum by the radioimmunoassay technique. The diagnosis was proved by laparotomy. In another 25 suspected cases beta-hCG values were less than 1 mU/ml, and in those cases the diagnosis was excluded.

Ectopic production of beta-subunit of human chorionic gonadotropin in malignant lymphoma.
Zentralblatt fur Pathologie, 1992Ectopic production of human chorionic gonadotropin (HCG) in tumor cells is an uncommon phenomenon that has rarely been documented. The immunoperoxidase method was used to demonstrate the presence of beta-subunit of HCG in malignant lymphoma cases, using paraffin-embedded sections of lymph nodes. 3 of 11 cases of malignant lymphoma (27%) were positively

Total human chorionic gonadotropin versus free beta-subunit in fetal aneuploidy screening
2000The levels of intact chorionic gonadotropin and its free beta subunits are eleveted in maternal serum of pregnancies with trisomy 21, and lower in trisomy 18 or 13. The objective was to evaluate the usefulness of total chorionic gonadotropin (ThCG) and free beta-subunit (free beta hCG) in non-invasive detection of fetal aneuploidy. In 213 women aged >/=
