A rapid, flow-through, column, nonequilibrium radioimmunoassay for human chorionic somatomammotropin (HCS) is described. The total incubation time is about 1 hour, and no centrifugation is needed. Reproducibility, sensitivity, specificity, recovery, and parallelism are adequate for clinical utility. Hormone levels in a variety of pregnancy sera assayed by this column method are closely related to results from another more conventional radioimmunoassay method.

Radioimmunoassay for serum myoglobin.
TLDR
Serum myoglobin levels were elevated when serum was taken up to 12 hours after myocardial infarction and generally elevated up to 24 hours, which probably indicates continuedMyocardial damage or new attacks. Expand

TLDR
Columns of Sepharose-coupled antibody to HCS have been used to purify labeled and unlabeled hormone by affinity chromatography prior to radioimmunoassay, resulting in a five hundredfold increase in ultimate sensitivity for the hormone. Expand

TLDR
It appears that some of the variation in FSH values reported from dosing rabbits immunized with human pituitary FSH may be attributed to variability of the trace protein, isotope, temperature, or time of incubation. Expand
Improved method for the extraction and purification of human growth hormone.
TLDR
A simple method has been devised for the extraction and purification of human growth hormone (HGH) from acetone-dried pituitary glands and it can be applied to extracting clinically useful HGH from embalmed pituitsary glands in a yield of 13–22 IU/g of pituitaries powder. Expand

TLDR
Commercial pregnancy HCG preparations do not reliably give pregnancy specific antisera when injected into rabbits, and these reagents were used to evaluate pregnancy specificity by immunodiffusion, immunoelectrophoresis and hemagglutination. Expand
Gel entrapment of antibody: a new strategy for facilitating both manual and automated radioimmunoassay.
TLDR
A technique of radioimmunoassay is presented that eliminates pipetting and centrifugation, and excludes interferences by high-molecular-weight materials from the incubation and separation steps, and has been successfully applied to the assay of angiotensin I and insulin. Expand

TLDR
Circulating hGH in patients with acromegaly was measured by a radioreceptor assay (RRA) and the results compared to those obtained by radioimmunoassay (RIA) with two different antisera, with both measurements exceeding RRA quantitation of hGH. Expand

TLDR
It is demonstrated that successful application of affinity chromatography in many cases will critically depend on placing the ligand at a considerable distance from the matrix backbone. Expand
