General description

Coomassie Brilliant Blue stain is widely used for the detection of proteins in sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE).[1] 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.[2] It is effective in staining anterior capsule in cornea with relatively less toxic effects.[3]

Application

Brilliant Blue G - Colloidal Concentrate has been used in the staining
  • protein fragments post in vitro pepsin digestion[4]
  • ovarian tumor fluid proteome prior to profiling[5][6]
  • the transcription factor (TFIID) complex from Saccharomyces cerevisiae[7]

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.

Katanins are microtubule (MT)-severing AAA proteins with high phylogenetic conservation throughout the eukaryotes. They have been functionally implicated in processes requiring MT remodeling, such as spindle assembly in mitosis and meiosis, assembly/disassembly of flagella and cilia and neuronal morphogenesis.

Protocols

Brilliant Blue G – Colloidal Concentrate Protocol

Brilliant Blue G-Colloidal Concentrate stains proteins in IEF, PAGE, and SDS-PAGE gels after electrophoresis, enhancing sensitivity with protein fixation.

Questions

1–6 of 6 Questions  

  1. How would you recommend that I reconstitute Product B2025, Brilliant Blue G?

    1 answer

    1. One bottle of the product makes 1 liter of working solution.  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.

      Helpful?

  2. What is the detection limit of Product B2025, Brilliant Blue G?

    1 answer

    1. The detection limit for proteins is about 50 ng of protein. However, proteins pick up stains differently so this is a general description and may not apply to all proteins

  3. 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.

  4. What is the solution stability of Product B2025, Brilliant Blue G?

    1 answer

    1. Once diluted the solution should be stable indefinitely.  It should be stored in the refrigerator and shaken well before each use.  The solution tends to precipitate on standing and heat accelerates precipitation.  Therefore, do not leave the bottle at room temperature overnight.

  5. Can you use Product B2025, Brilliant Blue G, with nitrocellulose?

    1 answer

    1. Use with nitrocellulose is not recommended, due to the methanol.
