The timing of the measurement of biological samples (e.g. biomarkers) is not always standardized. Biomarkers are the focus of many recent studies and treatments. The purpose of this study was to determine the timing of the release of beta-endorphin…

An improved radio-immunoassay using an antiserum directed towards the N-terminal part of the endogenous opioid peptide beta-endorphin 1-31 (beta-EP) was validated and applied to a study of beta-EP in plasma during ischaemic pain. Experimental…

Endomorphin (EM)-1 and EM-2 are opioid tetrapeptides, reported within the central nervous system, which have very high specificity and affinity for the mu-opioid receptor. We have used newly developed and well-characterised radioimmunoassays (RIAs)…
