A partition assay is described which allows a rapid determination of juvenile hormone release by insect corpora allata. Newly synthesized and released methyl-labeled C,, juvenile hormone is quantitatively extracted into an isooctane phase, whereas precursor methyl-labeled L-methionine remains in the

β¦ Synopsis
A rapid new assay is proposed for analyzing insect juvenile hormone esterase activity. The assay is based on > 99% of radiolabeled juvenile hormone being extracted into an isooctane phase while > 9% of the juvenile hormone acid remains in the basic aqueous-methanol phase. The assay is more rapid and less expensive than conventional chromatographic assays while yielding almost identical values of similar precision. This is the first rapid assay proposed for isomerically pure, commercially available juvenile hormone I.

An assay is reported for prolyl 3-hydroxylase activity. The method is based on the release of tritiated water (THO) during 3-hydroxylation of a 2,3-T-~proline-labeled (T = tritium) polypeptide substrate in which all prolyl residues recog nized by prolyl 4-hydroxylase have been converted to 4-hydroxy
