Thermo Fisher, J64297.18, Brilliant Blue R

Quantity: 50 g Brilliant Blue R is used for detection of protein bands following electrophoresis. It is a sensitive stain for protein detection in polyacrylamide gels, typically giving blue bands on a clear background with a sensitivity of 50-100 ng/band. It may be combined with other stains, such as silver stain, to distinguish different types of proteins. It displays metachromasia by appearing pink-red, rather than blue, when binding certain proteins, such as collagen and histone H1. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
