Questions

1–6 of 6 Questions  
  1. How is Product B2025, Brilliant Blue G, better than other Coomassie Blue dyes?

    1 answer
    1. The major advantage of the colloidal form is that it gives less background staining that the "regular" non-colloidal Coomassie Brilliant Blue G and Brilliant Blue R stains. Sensitivity can be markedly increased by double staining, first with Coomassie Brilliant Blue G Colloidal, then Rapid Silver Stain.
