Plasma measures of B-endorphin-like immunoreactivity in depressives and other psychiatric subjects
(Elsevier, 2006-04-07)
We report the utilization of a very sensitive radioimmunoassay for plasma B-END, which has enabled us to examine the suppressibility of B-END-like material, under dexamethasone challenge, on a population of depressed ...
The signal peptide of pro-opiomelancortin: Validation of a specific radioimmunoassay
(Elsevier, 2006-04-07)
The N-terminus portion of the POMC leader sequence (signal peptide) was synthesized, and an antiserum was raised against it. A radioimmunoassay was developed which is effective at a dilution of 1:500,000, and sensitive at ...
