Stain Free Gels Confirm Protein Purity

Stain Free Gels Confirm Protein Purity

A proven method for confirming protein purity and yield without the need for gel staining steps. Stain-free gels provide visual confirmation of protein purity and yield by gel electrophoresis in less than 30 minutes. Stain-free technology is perfect for drug discovery, drug development, and method development for preclinical research.

How does stain-free technology work?

Stain-free gel chemistry uses a unique compound, which, when activated, reacts with tryptophan residues in your protein sample to emit a fluorescence signal. This allows the quick visualization of proteins without any staining steps.

Stain-free gels are available in both handcast and precast gel formats:

FastCast™  Handcast Gels

  • Ready to run in as little as 30 min
  • Remain fresh for up to 4 weeks at 4°C
  • All the benefits of TGX Stain-Free technology, including fast run times and stain-free visualization of proteins in 5 min

Precast Gels

  • Available in mini and midi precast gel sizes
  • Run up to 26 samples on a single gel
  • All the benefits of TGX Stain-Free technology, including fast run times and stain-free visualization of proteins in 5 min
