Red pigment concentrating activity of the sinus gland extracts, pre-incubated with the anti-AKH serum code 241 ( : untreated extracts; - -: pre-incubated extracts; A: 1 SG equivalent/10 Ml; B: SG equivalent/10^1). DISCUSSION The detection of RPCH/AKH-like material in the eyestalk of the prawn Palae- mon serratus was based on the chemical relationship which exists between the crusta- cean RPCH and the insect hormone AKH. The molecular structure of the AKH (Stone et al, 1976) closely resembles that of the RPCH (Fernlund, 1974) and these two substances "reproduce each other's biological effects when cross-tested on mem- bers of the two arthropod groups" (Mordue and Stone, 1976). These properties sug- gested the use of two different anti-AKH sera to reveal the sites producing and storing RPCH/AKH-like material in the eyestalk of the prawn and to compare the biological activities of tissue extracts with those of synthetic AKH and RPCH. The antisera used were raised in rabbits against (Tyr1) - AKH (Tyr-Leu-Asn-Phe- Thr-Pro-Asn-Trp-Gly-Thr-NH2) coupled through its N-terminal to thyroglobulin (code 241) and against the AKH (1-4) peptide (pGlu-Leu-Asn-Phe) also coupled to thyroglobulin through its C-terminal (code 433) (Schooneveld et al., 1983, 1985b, chr. stag* 5 chr. stage.
