General description

Coomassie Brilliant Blue stain is widely used for the detection of proteins in sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE). Staining with brilliant blue G is called as blue silver staining due to its improved sensitivity close to silver staining method. Coomassie Brilliant Blue G stain associates with proteins via hydrophobic interaction. It is effective in staining anterior capsule in cornea with relatively less toxic effects.

Application

Brilliant Blue G - Colloidal Concentrate has been used in the staining
  • protein fragments post in vitro pepsin digestion
  • ovarian tumor fluid proteome prior to profiling
  • the transcription factor (TFIID) complex from Saccharomyces cerevisiae

Reconstitution

The suspension will contain 0.1% (w/v) Brilliant Blue G, 0.29 M phosphoric acid and 16% saturated ammonium sulfate after diluting to 1 liter with 800 mL water.

Analysis Note

This product has been tested for suitability on SDS-PAGE.

Protocols

Brilliant Blue G – Colloidal Concentrate Protocol

Brilliant Blue G-Colloidal Concentrate has been designed for post-electrophoresis staining of proteins in IEF, PAGE, and SDS-PAGE gels. Fixing the proteins prior to staining is recommended for maximum sensitivity.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
