Radioimmunoassay of peptide hormones

Radioimmunoassay kits for thyroid hormones.

Characteristics of the T4 and T3 radioimmunoassay kits that are commercially available in the UK are described. Useful comparative data and criticism are given about many of these kits. Some unacceptable variation in accuracy is demonstrated.

New Solid Phases for Estimation of Hormones by Radioimmunoassay Technique

The efforts in this study were initiated to develop and validate new solid phases for estimation of hormones by radioimmunoassay (RIA). The study argued the successful application of different hydroxyapatites (HAP) as new solid phases for estimation of Alpha fetoprotein (AFP), Thyroid Stimulating hormone (TSH) and Luteinizing hormone (LH) in human serum. Hydroxyapatites have different alkali ea...

Radioimmunoassay of thyroid related hormones and TSH in primary hyperthyroidism.

One hundred and forty seven clinically proven hyperthyroid subjects were studied using radioimmunoassay techniques for the estimation of serum thyroid hormones and pituitaryTSH concentrations. In females toxic goitre was more frequently seen in the age group 21 to 30 years and in males 31 to 40 years. The mean levels for serum T4, T3, FT4 and FT1 were significantly elevated while the mean level...

Radioimmunoassay for neurotensin, a hypothalamic peptide.

A highly sensitive and specific radioimmunoassay for neurotensin has been developed which utilizes 125I-labeled neurotensin and rabbit antisera raised toward synthetic neurotensin which has been coupled specifically through its lysine side chain to several proteins. The three antisera described have different specificities but are directed primarily towards the COOH-terminal region of neurotens...
