Abstract:
:Gonadotropins (GTH) were isolated from pituitary glands of grass carp and their properties investigated. Acetone-dried pituitaries were extracted with ammonium acetate-ethanol and were then passed through cation exchanger, anion exchanger, and gel filtration column. Two glycoprotein gonadotropins (DE I and DE II) were isolated of MW 56,000 and 53,000 daltons, respectively, as determined by gel filtration technique. Isoelectric points of the two GTHs also differed from each other. Sialic acid contents were 3.64% and 1.47% for DE I and DE II, respectively. Both GTH's stimulated, in a similar manner, testicular androgen and ovarian estradiol synthesisin vitro.
