  • Solution for fast visualization of protein
    Patent number: 6555382
    Abstract: The present invention provides an improved solution for staining proteins in and/or on a solid matrix or support. Typically, a protein-containing gel or membrane may be washed in a hot solution of water for about five minutes, stained in a hot solution of COOMASSIE brilliant blue dye in dilute aqueous mineral acid for about five minutes, and then rinsed in water. The washing and/or staining steps may be performed by placing the gel in a wash and/or staining solution, respectively, heating the solution in which the gel is placed to boiling in a microwave oven, and incubating the gel in the solution for about five minutes. The entire procedure can be performed in a little over ten minutes, which represents an enormous time savings over existing methods.
