Gel Negative-Staining Kit for Rapid and Highly Sensitive Protein Detection
Detecting protein bands in a polyacrylamide gel after electrophoresis requires the gel to be stained. Common staining methods include Coomassie Brilliant Blue staining, silver staining, fluorescence staining, and negative staining. Negative staining is a method in which only regions of gel containing protein remain unstained, while the remainder of the gel is stained white.1) Bands can be visualized by placing the gel against a dark background.
Gel Negative Stain kit (1) can be used to detect protein bands with high sensitivity in as little as 20 minutes. Furthermore, stained gels can easily be destained using the included destaining solution, with the destained gel is able to be used in further downstream applications, such as Western blotting and mass spectrometry.2,3)
