摘要
A nitrocellulose-based assay was de,eloped using a dot-blot apparatus to detect phenoloxidase activity in column fractions. Using this assay, plasma phenoloxidase was partially purified from Aedes aegypti larvae using hydrophobic interaction chromatography, gel filtration, and ion-exchange chromatography. The molecular weight (M(r)) native enzyme was 130,000, and it contained subunits of 76,000, 62,000, and 58,000. Two phenoloxidase peaks were observed by ion exchange chromatography, and these Fractions had distinct polypeptide profiles as detected by SDS-PAGE.
