Use a gel fixing solution. Proteins have ran off the gel. Use a SDS-PAGE gel with a higher % acrylamide. Proteins are degraded. Make sure there is no protease contamination. Ensure the samples did not freeze-thaw. The small-peptides (<4 kDa) did not fix in the gel. Fix the gel with 5% glutaraldehyde. Rinse the gel well with water before staining.

The aim of this study was to adapt a proprietary decellularisation process for human dermis for use with porcine skin. Porcine skin was subject to: sodium chloride (1 M) to detach the epidermis, trypsin paste to remove hair follicles, peracetic acid (0.1% v/v) disinfection, washed in hypotonic buffer and 0.1% (w/v) sodium dodecyl sulphate in the …

3. Sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis a. After pouring the SDS polyacrylamide gel, you realize that instead of 2 ml, you used 4 ml of 30% acrylamide/bisacrylamide solution for the preparation of the separating gel (in both cases for 5 ml, total gel volume).
