Fig. 2From: Selective extraction of recombinant membrane proteins from Hansenula polymorpha by pulsed electric field and lytic enzyme pretreatmentSDS PAGE (А) and Western blot (B) analysis of extracts from electrically treated cells obtained after 75 min incubation with 0.5% Tween 20 or 0.5% Triton X-100. Lane M, molecular weight marker; lane 1, soluble fraction obtained after incubation of the cell suspension (125 mM PPB, pH 8) for 75 min with 0.5% Tween 20 at room temperature; lane 2, 0.5% Тriton X-100 at room temperature; lane 3, 0.5% Tween 20 at 39 oC; lane 4, 0.5% Тriton X-100 at 39 oC. The same volumes of extracts obtained from cell suspensions with equal cell concentrations are loaded on to each laneBack to article page
