MIH specifically binds to membranes of mature female hepatopancreas with higher binding at mid-vitellogenic stage than pre-vitellogenic. A) Specific binding of [125I] MIH to various tissue membranes of vitellogenic females and YO and hepatopancreas of juveniles. B) Specific binding of [125I] CHH to the same membranes. All membranes were prepared from five animals, except for J- YO membranes that were prepared from 700 intermolt animals. F, Females; M, Males; J, juveniles; HP, hepatopancreas; 1, 2, and 3 refer to the ovarian stages; F-ovary- ovarian membrane of females at ovarian stage 3. Results are presented as mean ± SEM of the triplicates as % of the J-YO. The alphabetical letters show the significant differences at P < 0.05.
