A radioimmunoassay method for determination of fish plasma insulin.

Radioimmunoassay of insulin in serum and plasma.

Paired serum and plasma samples from subjects were analyzed to determine if there was a difference in the insulin content of serum and plasma. Although there was no difference in the serum and plasma insulin concentrations in the samples as a group, there were differences in the serum and plasma insulin concentrations in individual subjects. Recovery of radioimmunoassayable insulin from clotted...

A photometric method for the determination of insulin in plasma and urine.

Simple extraction method and radioimmunoassay for somatostatin in human plasma.

Interference by human plasma proteins in the radioimmunological determination of somatostatin was eliminated by subjecting plasma samples to acid--ethanol precipitation. The assay was performed on the lyophilized supernate from 300 microliters of human plasma, with reagents that are commercially available. Sensitivity was 2.6 pg, corresponding to 8.7 ng/L of plasma. The intra-assay CV was 8%; t...
