【What’s characteristic of Acid Black ATT】

Acid Black ATT Staining of proteins on polyacrylamide gels, agarose gels and cellulose nitrate membranes. After electrophoresis, it is recommended to fix the protein on the glue. The glue was stained with 7Chemicalbook%(v/v) acetic acid solution of 0.1% amino-black 10B for at least 2 hours and then decolorized with 7%(v/v) acetic acid solution. The detection sensitivity is approximately 20% of the Coomath Bright Blue R250. Chemical property
