Abstract

Storage protein-1 (SP-1) of Gallerio mellonella was identified in hemolvmph and fat body by electrophoresis. SP-1 was purified from hemolvmph by KBr density gradient ultracentrifugation , DEAE-cellulose (DE52) ion-exchange chromatography, and gel permeation chromatography (Sephadex G-200). Purity of SP-1 was confirmed by Non-SDS PAGE and electron microscope. SP-1 is 9.4 nm in diameter and regular octahedron in shape. SP-1 has isoelectric point of 5.7 and native molecular weight of 365 K dalton and is composed of one type of subunit with molecular weight of 82 K dalton. Ttiacylslvcerol and phospholipid were found to be maior lipid components in SP-1.
