G-Biosciences' Reversible Copper Stain™ is a single step stain for rapid detection of proteins resolved on SDS-PAGE


G-Biosciences' Reversible Copper Stain™ is based on the interaction of copper ions with polyacrylamide and proteins. It works by depositing a copper metal precipitate in the gel, resulting in an opaque blue/green gel, while the SDS coating on the proteins inhibits copper ions from binding to the proteins. A negative image of the gel is produced; consisting of clear protein bands visualized against a semi-opaque blue/green polyacrylamide background.


Protein bands are visualized in as little as 5 minutes. The sensitivity of the Reversible Copper Stain™ is 0.1-0.5ng BSA protein. Staining does not interfere with the electroelution of proteins or alter their biological properties. Gels stained with the Reversible Copper Stain™ can be destained in 20-25 minutes before the transfer or electroelution of proteins. The kit contains ready to use reagents for 25 mini gels and is supplied with a destainer.


No destaining is necessary. Reversible Copper Stain™ is suitable for the staining of protein gels prior to transfer or electroelution of proteins, but is not suitable for native gels or gels containing Tricine or Glycine.
