Title: Tissue distribution and purification of prophenoloxidase in larvae of Asian Corn Borer, Ostrinia furnacalis Guenee (Lepidoptera: Pyralidae). Author: Feng CJ, Fu WJ. Journal: Acta Biochim Biophys Sin (Shanghai); 2004 May; 36(5):360-4. PubMed ID: 15156278. Abstract: Using ammonium sulphate precipitation, Blue-Sepharose CL-6B, Phenyl-Sepharose CL-4B, prophenoloxidase (PPO) was isolated and purified from hemolymph of Ostrinia furnacalis larvae. This zymogen was a heterodimer, and composed of two subunits with the relative molecular mass ranging from 66.2 kD to 97.4 kD determined by SDS-PAGE. Western blotting and indirect immunofluorescence test showed that PPO was present in integument, hemolymph plasma and cell membrane of granular hemocytes and oenocytoids of O. furnacalis larvae.[Abstract] [Full Text] [Related] [New Search]
