Western Blotting

Western Blot University

Courses designed to make you a western blotting expert.

Stain-Free technology is superior to conventional western blotting methods as it allows users to:

  • Visualize gels minutes after electrophoresis
  • Perform quality assessments at each step without the need for additional staining and destaining
  • Increase accuracy and produce reliable quantitative results via total protein normalization
