一般說明

考马斯亮蓝染色剂在十二烷基硫酸钠聚丙烯酰胺凝胶电泳 (SDS PAGE) 中被广泛用于蛋白质的检测。[1]亮蓝 G 染色因其灵敏度接近银染法而被称为蓝银染色。考马斯亮蓝 G 染色液通过疏水作用与蛋白质结合。[2]它可以有效染色角膜前囊膜,毒性相对较小。[3]

應用

亮蓝 G-胶体浓缩液用于在分析酿酒酵母中的[4][5]
  • 转录因子(TFIID)复合物前,进行体外胃蛋白酶消化后卵巢肿瘤液蛋白质组中
    • 的蛋白质片段的染色[6]
    • [7]

  • 重構

    用 800 mL 水稀释至 1 L 后,混悬液将含有 0.1% (w/v) 亮蓝 G、0.29 M 磷酸和 16% 饱和硫酸铵。

    The basal transcription factor TFIID is composed of the TATA-binding protein (TBP) and 14 TBP-associated factors (TAFs). Although TBP alone binds to the TATA box of DNA and supports basal transcription, the TAFs have essential functions that remain poorly defined.

    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.

        Helpful?

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

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

        Helpful?

    6. What is the Department of Transportation shipping information for this product?
