چکیده
In sea bass (males and non-vitcllogcnic females) estradiol (E2) treatment caused the appcarnnce in the bloodstream of a new protein that was identified as the vitellogenin (VTC) moleculc for this teleost spccies. The molecular weight of the sca bass VTG (445 kDa) and its amino acid composition was similar to that of other teleosts. VTC was purified by doublcstep chromatography and then used to obtain specific antibodies. The localization of VTG in the liver and in the ovary was carried out by immunocytochemistry. The effects of the E2 treatment on the synthetic activity of the liver wcrc studied throughout thc modifications observed at the histological and biochemical levels.

Polyphenol oxidase from Black mulberrys was extracted and partially purified through (NH4)2SO4 precipitation, dialysis and ion exchange chromatography. P-cresol was the better substrate for cresolase activity with a Km (11.5 mM) and catechol for catecholase activity with Km (6.4 mM) at pH 5. Km for cresolase and catecholase activity of IsoPPOII at pH 6.5 were 12 and 8.5 and for IsoPPOIII at pH ...
