Abstract

, Jel proteinlerin elektroforetik yöntemlerle ayrılması ardından çeşitli boyama yöntemleri ile tespit edilebilir. Bu birim, dört popüler yöntem proteinleri tespit etmek için protokoller açıklar. Coomassie mavi boyama, kolay ve hızlı bir yöntemdir. Gümüş boyama, daha fazla zaman tüketen, çok daha hassas ve böylece küçük miktarlarda protein tespit etmek için kullanılabilir. Coomassie boyama daha duyarlı ve genellikle gümüş boyama gibi hassas başlıca nedeni, floresan boyama, geleneksel boyama işlemleri için popüler bir alternatif. SYPRO Portakal ve SYPRO Ruby ile protein boyanması da burada gösterilmektedir.

  4. A good and cheap alternative to SYPRO Rubi is RuBPS staining. Here are some protocols. More information can be found on www.ruthenium.ag.vu   RuBPS staining protocol I (quality) 1. Fix the gel in 30% EtOH, 10% acetic acid overnight ². Rinse the gel in ²0% EtOH for 30 min and repeat 3 times 3. Incubate the gel in 1 mM RuBPS solution for 6 h 4. Equilibrate the gel in water for 10 min and repeat once 5. Destain the gel with 40% EtOH/10% acetic acid for 15 h 6. Equilibrate the gel in water for 10 min repeat once and scan   all% are in V/V   Procedure as published in Proteomics ²004, 4, 599–608.     RuBPS staining protocol II (fast)   1. Incubate the gel in 50 ml of 40% Ethanol/10% acetic acid containing    1 mM RuBPS for 1 h. ². Destain the gel for ²0 min in 40% Ethanol/10% acetic acid 3. Wash the gel for 10 min in water and scan   all% are in V/V   Procedure as published in PLoSONE. ²007 Feb ²8;²(²)e²63.       RuBPS staining protocol III (co-electrophoretical)   1. Add 1 ml of ²0 mM stock solution to one pocket of your SDS gel. Run     the gel according to your standard procedure. ². Incubate the gel in 50 ml of 40% Ethanol/10% acetic acid for ²0 min 3. Incubate the gel in 50 ml water for 10 min and scan       RuBPS staining protocol IV (loading buffer)   1. Add 1 ml of ²0 mM stock solution to your loading buffer (omit all other     dyes like bromophenol blue). Run the gel according to your standard     procedure. ². Incubate the gel in 50 ml of 40% Ethanol/10% acetic acid for ²0 min 3. Incubate the gel in 50 ml water for 10 min and scan
