บทคัดย่อ: Mouse antiserum against C-terminal amide of Pem-CMG (a peptide in the family of CHH/MIH/GIH) penta-deca peptide (RPRQRNQYRAALQRLamide=CMG-15) was generated and used for localization of the peptide in tissue and extract of the eyestalk of Penaeus monodon by means of immunohistochemistry and dot-ELISA in comparison with anti-T+ antiserum (T+=YANAVQTVamide: the putative C-terminal amide of crustacean hyperglycemic hormone (CHH) of Macrobrachium rosenbergii). The anti-CMG-15 antiserum did not show cross-reactivity to T+ peptide by dot-ELISA and vice versa for anti-T+ antiserum. In dot-ELISA of eyestalk extract of P. monodon after one step separation by RP-HPLC, anti-CMG-15 antiserum recognized different peptide fractions (F38-39) from those recognized by anti-T+ antiserum (F19, 40-41 and 47-51). Most of the T+ immunoreactive fractions (except F19) show higher hyperglycemic activity than the CMG immunoreactive fractions. In immunohistochemical localization, anti-CMG antiserum recognized only 2-3 neurons in medulla terminalis X-organ complex (MTXO) with long processes terminated in the sinus gland. The CMG-immunoreactive neurons were clearly distinct from CHH containing neurons situated in the same area. This evidence confirms the existing of CMG peptide which may play distinct roles from CHHs in hormonal regulation in P. monodon. © 2002 Elsevier Science Inc. All rights reserved.
