Two vitelline envelope precursors (choriogenin H: Chg H; choriogenin L: Chg L) and an egg yolk precursor
(vitellogenin B: VgB) were purified from red lip mullet. The mass of intact Chg H and Chg L were estimated to
be ~215 kDa and ~69 kDa, respectively. In SDS-PAGE, Chg H and Chg L separated to positions corresponding
to ~51 kDa and ~44 kDa, respectively.
