Measurement of Human Growth Hormone Using a Chemiluminescence Assay and a “Glow” Luminometer

Measurement of human growth hormone using a chemiluminescence assay and a "glow" luminometer.

The gene that codes for human growth hormone (hGH) is used as a reporter gene to assess changes an effector may have on gene expression of a specific DNA sequence (6). hGH is secreted into the medium of transfected cells following the addition of an appropriate effector; measurement of hGH levels allows for quantification of the degree of activation (or suppression) of gene expression relative ...

Immunofunctional assay of human growth hormone (hGH) in serum: a possible consensus for quantitative hGH measurement.

Confirmation of the diagnosis of GH deficiency in adults and children involves provocative testing for human (h) GH. Different commercially available immunoassays yield largely discrepant results in the measurement of GH levels in human serum. These discrepancies result in doubtful relevance of cut-off levels proposed for GH provocative testing. We have developed an immunofunctional assay metho...

An ln vivo Assay for Biological Activity of Synthesized Recombinant Human Growth Hormone

A radio-immunoelectrophoretic assay for human growth hormone.

A number of attempts have been made to measure the amount of growth hormone in human plasma or in extracts thereof. By using the tibia-line biological assay Gemzell (1959) and Forsman & Gemzell (1959) detected growth hormone in extracts from subjects with acromegaly or diabetes but not in extracts of normal plasma. Owing to the lack of sensitivity and specificity of biological assays for growth...
