Determinação do perfil protéico da membrana externa da Leptospira interrogans sorovariedade Hardjoprajitno

Abstract

The protein profile of the outer membrane of Leptospira interrogans serovar Hardjoprajitno was determined by two-dimensional gel electrophoresis. The outer membrane was extracted with Triton × 114 and the proteins were precipitated with acetone. The images were analyzed for the determination of the molecular weight of the detected proteins. Thirty-five spots for the proteins that are predominant in the outer membrane of this Leptospira were observed and five proteins were found in higher quantities: 22.54KDa (LipL22), 30/26KDa (LipL32), 34.41KDa (PME34) (2), 42.75KDa (LipL41), and 58.59KDa (LipL63). © 2009 Escola de Veterinária UFMG.
