“…Its ICso (con centration inhibiting binding by 50%) was 8-10 nM compared to about 3 nM for MeTRH and 30nM for TRH. These data are con sistent with relative potency data reported by Felix et al [9], Tritiation New England Nuclear dissolved 20 mg of precursor in 0.2 ml of methanol and stirred it with 8 mg of PdO catalyst under an atmos phere of tritium gas for 3.5 h at 25 °C. The sample incorporated 3.64 Ci of tritium, corresponding to a nominal specific activity of about 70 Ci/mmol for the crude product.…”

“…Custom synthesis of [3-Me-His2,dehydro-Pro3]TRH was per formed by Peninsula Laboratories according to Felix et al [9], The product showed one major spot by TLC in five solvent systems. We also tested the compound for its ability to compete for binding of 8 nM [3H]TRH to sheep anterior pituitary receptors.…”
