Specific 125I radioimmunoassay for morphine. 1986

D J Edwards, and Z Popovski, and T J Baumann, and B A Bivins

In this specific radioimmunoassay procedure for morphine, samples are first subjected to an extraction procedure to remove the major metabolite of morphine (morphine-3-glucuronide), then quantified by use of a commercial radioimmunoassay kit with 125I-labeled morphine. Concentrations between 10 and and 100 micrograms/L are routinely measured with a within-run CV of less than 2.0% and a between-run CV of 3.5%. This rapid, specific, and sensitive method requires minimal technical skills and analytical equipment that is common to most laboratories.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
