Cell membranes of locust hindgut and oviduct solubilized in HEPES buffer containing 1% digitonin retained their [3H]-proctolin binding activity. Preparative isoelectric focussing (IEF) of either hindgut or oviduct solubilized membranes yielded a sing

The treatment of locust abdominal fat body in vitro with octopamine caused an elevation in cyclic 3′, 5′-adenosine monophosphate (cAMP). However the values varied from one tissue sample to another. Incubation of air sacs separated from fat body c

The locust oviduct bioassay system was used to assess the ability of a variety of peptides to induce oviductal contractions. Proctolin analogues were three orders of magnitude less potent than proctolin. Proctolin supra-analogue and Arg-Tyr-Leu-Ala-T

Immunocytochemical staining of the nervous system of larva, pupa, and adult stage of Tenebrio molitor with anti-insulin serum demonstrated insulin-like peptides in the protocerebrum, corpora allata, and suboesophageal ganglion. During pupal developme

The binding of [ 3 H]proctolin to oviduct membranes has been analyzed to investigate the nature of proctolin binding sites in the oviduct. Proctolin binding was found to be time dependent, proportional to concentration of membrane protein, saturable,

The binding of [ 3 H]proctolin to hindgut membranes of the locust was investigated. Specific proctolin binding was found to be time dependent, proportional to membrane protein concentration, saturable and reversible. Scatchard analysis of the binding

Proctolin was incubated in vitro with crude membrane preparations derived from hind gut and ovary of Locusta migratoria. The metabolites of proctolin were separated and identified by reversed phase-high performance liquid chromatography which allowed

A number of proctolin analogs modified at position three were analyzed for their relative binding affinities and biological activity on locust hindgut and oviduct. A decrease in chain length at this position (from Leu, Ile to Val) or an increase in h

The control of oviposition in the locust involves the expulsion of eggs from the lateral oviducts, a process believed to be under neurohormonal control. In this paper we have attempted to identify this putative hormone. Immunohistochemical staining o
