Method for visualizing biomolecules, such as proteins or nucleic acids, with the unaided eye, without needing to use potentially toxic compounds, exposure to ultraviolet (UV) light or fluorescence
The present invention relates to a method of visualizing biomolecules, having the steps of: a) providing a sample of immobilized biomolecules in a matrix and carry on the electrophoresis process; b) incubating the matrix of step a) in a solution containing a cyanine-derived molecule, for a time of 5 to 60 minutes, at room temperature, in a container preventing exposure to light, shaking the container at less of 75 rpm; c) transferring the matrix from step b) to a container with a solution having: at least one tetrazolium salt and incubating for a time of 15 to 120 minutes at room temperature under light exposure; d) removing the matrix with immobilized biomolecules from the previous step and washing with distilled water; and e) visualizing directly by the naked eye the biomolecules immobilized in the matrix.
