Determination Protein Expression Western Blotting Lab Report

Western blotting uses specific antibodies to identify proteins that have been separated based on size by gel electrophoresis. The immunoassay uses a membrane made of nitrocellulose or PVDF (polyvinylidene fluoride). The gel is placed next to the membrane and application of an electrical current induces the proteins to migrate from the gel to the membrane.

Effect of temperature and SDS concentration on cell ...

C. The extreme fluidity of the membrane caused the betacyanin to leak out because the cell was unable to maintain its structure, and therefore lost cell integrity. Detergents can be used to remove proteins from cell membranes, (Freeman, 2002) the absence of proteins destroys the cell membrane structure which makes it lose its integrity.
