Stain

Introduction of Protein Stain

In biochemical experiments, the most important obstacle faced is obtaining high-purity and high-yield proteins. It is convenient for the experiment to be able to directly and rapidly detect and observe the quality change of the protein once it has been stained. By staining proteins separated on gels, key properties of these biopolymers, such as molecular weights and/or charges, can be determined. By utilizing staining, proteins can be detected on gels and blots. Different stains vary in color, sensitivity, stability, ease of use, specificity, and versatility. Commonly used protein staining reagents are divided into organic reagent staining represented by Coomassie brilliant blue(CBB), silver staining, fluorescent staining, and isotope color development.

Total Protein Staining Methods

• CBB Staining
• Colloidal Coomassie Staining
• Silver Staining
• Zinc Staining
• SYPRO

CBB and silver staining are frequently used in traditional protein staining, and the comparison of the two is as follows.
