| abstract |
Biomolecules contained in gels or on membranes can be stained or labeled, without direct contact with toxic staining solutions, by applying to the gel or membrane an article of manufacture comprising a flexible backing with a coating that contains a stain or label. During the application, the stain or label is transferred from the backing to the biomolecules, marking them. The volume of the staining solution in this procedure is minimized, and environmental hazards are reduced. Furthermore, ease of manufacture reduces the cost of the article. |
