Figure 2. Western blot analysis of trypsin treated oral insulin preparation solution.
This figure demonstrated the extension of insulin in trypsin treated insulin preparation solution. It was observed that trypsin was unable to degrade insulin in milk-insulin preparation solution. Here, Lane-A represented the pure insulin (insulin alone) band by western blot analysis where no trypsin was added and an arrow (→) indicated the positive band of insulin in Lane-A; Lane-B represented the insulin band in trypsin treated insulin preparation after 180 min and Lane-C represented trypsin treated milk preparation without insulin by western blot analysis using insulin antibody. From the Image-J analysis, it was found that 80.1% of insulin remained unaltered in lane-B compared to insulin (alone) in lane-A after 180 min where as no positive band was found in Lane-C.
