Abstract
A radioimmunoassay was developed using I-125-labeled- [Tyr(0)]Locusta- DH and polyclonal antibodies raised against Locusta-DH(29-46). The ass ay had a detection limit of 50 pM, and displayed limited crossreactivi ty for other CRF-related peptides, but not for unrelated peptides. Abo ut 60% of the total immunoreactive material in locust hemolymph was at tributable to Locusta-DH. The circulating level of diuretic hormone in creases fivefold in fed insects, sufficient to stimulate primary urine production, and is correlated with the duration of the meal. This is consistent with the role of Locusta-DH in the control of postfeeding d iuresis. (C) 1997 Elsevier Science Inc.
