[f. radio- 2 + receptor.]
†1. Written radio-receptor. A sensory receptor which responds to electromagnetic radiation of any kind. Obs.
1927[see mechanoreceptor]. 1935Brit. Jrnl. Psychol. XXV. 266 As Parsons describes, the receptors differentiated along three main lines, chemo-, radio-, and mechano⁓receptors.
2. radioreceptor assay, a radiological assay for hormones in which the test sample, together with a known quantity of radioactively labelled hormone, is allowed to bind to a standard preparation containing receptor sites.
1973Science 1 June 968 A radioreceptor assay with a sensitivity of 5 nanograms per milliliter has been developed for mammalian and avian pituitary prolactin, placental lactogenic hormones, and human growth hormones, using a membrane receptor preparation isolated from rabbit mammary glands. 1974Nature 29 Mar. 436/2 At this time the PL concentrations measured by radioreceptor assay were almost entirely due to the cross reaction of pituitary prolactin in the receptor assay. 1978Ibid. 20 Apr. 730/2 The fact that affinity to rat opiate receptors was demonstrated in the plasma using a radioreceptor assay..indicates that a loss of the postulated biological activity by metabolic or other processes can be excluded. |
