Gel electrophoresis is a method used in molecular biology to separate DNA and proteins through an electrical current applied based on molecular weight or fragment size. The various reagents, including molecular weight markers, blotting reagents, and stain removal reagents, improve the detection accuracy of electrophoresis results through enhanced visualization. The electrophoresis reagents offered are ideal for use in the fields of molecular biology, immunogenetics, and other molecular biology disciplines.
