2D-SILVER STAIN-II - for Electrophoresis -



For detection of proteins and nucleic acids migration by polyacrylamide gel electrophoresis, silver staining is now being highlighted as a sensitive staining method. However the original silver staining method is not necessarily easy to work and takes long-time. 2D-SILVER STAIN-II is an improved reagent kit developed to provide simple and fast staining.




2D-SILVER STAIN II is applicable to the detection of proteins and nucleic acids subjected to polyacrylamide and SDS-polyacrylamide slab gel electrophoresis.

Feature and Advantages

1. Rapid staining results in a short time after electrophoresis.
2. Staining with higher sensitivity For proteins:50 to 100 times more sensitive than CBB staining For nucleic acids: 50 to 100 times more sensitive than EB staining
3. Simple preparation and simple operation.
4. No use of such materials as heavy metals controlled by regulations.
5. Capable of restaining CBB-stained gels. (Double-staining)
6. Staining process can be stopped any time during development for desired chromatic figures.
