RESUMO
Estudou-se o perfil das proteínas da membrana externa (PME) da Leptospira interrogans sorovariedade Hardjoprajitno por meio da eletroforese bidimensional. Foram utilizadas técnicas de extração das PME com Triton x114 e precipitação com acetona. Os géis foram corados com nitrato de prata e as imagens analisadas para determinação da massa molecular das proteínas detectadas. Foram visualizadas 35 bandas protéicas, sendo que cinco delas se destacaram por estarem em maior quantidade: 22,54KDa (LipL22), 30/26KDa (LipL32), 34,41KDa (PME34), 42,75KDa (LipL41) e 58,59KDa (LipL63).
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 x 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).
