The molecular weight of the native lipase was estimated to be about 29 kD by gel filtration using Sephadex G 150, and that of the denatured lipase was determined to be about 27.5 kD by its mobility on SDS PAGE, indicating that the lipase was a monomer.

• SDS?PAGE 和凝胶过滤分别测得酶的分子量为27.；5 kD和29 kD， 表明该酶以单体形式存在。
