[Radioimmunoassay for human growth hormone].
Detailedmethodsfor: (1) 1311 iodination of human growth hormone (HGH); (2) purification of labeled HGH (HGH-139); and (3) radioimmunoassay of HGH are given. Bio-GeI filtration is introduced as a rapid and reproducible method for purifying HGH-1311which hasbeenobtainedby a modificationof the methodof Greenwood at al. (1). Highlypurified HGH-’311 with a bindability of 96% or more is usually achie...
متن کاملDevelopment of an in-house radioimmunoassay for human growth hormone.
A simple and sensitive double-antibody radioimmunoassay for human growth hormone (HGH) was developed, optimised and validated. The anti-hGH sera raised in 2 rabbits were highly specific with low cross-reactions of 0.19% and 0.3% with human placental lactogen and 0.21% and 0.13% with human prolactin. The mean sensitivity of the assay determined from 28 assays was found to be 0.4 +/- 0.2 mIU/L. M...
متن کامل[Radioimmunoassay of human growth hormone by adsorption to talc].
Radioimmunoassay of human growth hormone (HGH) using adsorption to talc was examined. Results are as follows: 1) The minimal detectable amount of HGH was 0.02 ng/ml. The mean recovery rate was 100.8%. Mean +standard error (S.E.) of the same two samples, repeatedly measured eight times, were 3.5+0.2 and 35.4+0.5 ng/ml, respectively . Concentrations of the same acromegalic plasma diluted in diffe...
متن کاملOvernight radioimmunoassay of human follicle-stimulating hormone.
A radioimmunoassay procedure for follicle-stimulating hormone in serum has been developed in which the assay mixture is incubated at 37#{176}C for a total of 22 h, rather than at 4#{176}C for 4-7 days. The withinassay coefficients of variation for the 37#{176}C and 4#{176}C methods, respectively, are 7.7% and 5.0%, while the between-assay variations are 13.8% and 9.9%. Comparison of values for ...
متن کاملRadioimmunoassay of human parathyroid hormone in serum.
A new radioimmunoassay for human parathyroid hormone (PTH) in serum, which can measure the hormone present in 94% of the normal sera tested, is described. It is based on the ability of human PTH to compete with (131)I-labeled bovine PTH for binding to an antiserum directed against porcine PTH. This antiserum distinguishes between human PTH extracted from parathyroid adenomata and that present i...
