Analysis of 1-D SDS-PAGE of the membrane proteins extracted using organic solvent procedure. Varying ratios of chloroform/methanol (0:9 to 9:0) were used and respective fractions were resolved in 12.5% polyacrylamide gel followed by CBB R-250 staining. M indicates the molecular weight markers. Shown are (A) the profile of insoluble proteins, (B) proteins soluble in organic phase, and (C) various phytopigments viz., Chla, Chlb and carotenoids in the corresponding organic phase of various ratios of chloroform/methanol. Each experiment was performed in triplicates with at least two biological samples.
