Thermo Scientific loading dyes
Loading dyes are essential for the preparation of DNA ladders, markers, and samples for loading on agarose or polyacrylamide gels. Depending on your DNA fragment of interest you can chose between different dyes that prevent DNA masking during gel exposure to UV light.
Thermo Scientific agarose
Agarose is a nontoxic polysaccharide extracted from seaweed. It is easy to use and relatively inexpensive. For DNA and RNA electrophoresis, high-quality agarose is needed to obtain sharp bands. Thermo Scientific TopVision Agarose is available in powder (standard and low melting point) as well as convenient and easy-to-use tablet formats.
Thermo Scientific buffers for electrophoresis
The electrophoretic mobility of DNA molecules depends on the applied voltage as well as the composition of the electrophoresis buffer. Thermo Scientific offers Tris-borate-EDTA (TBE) and Tris-acetate-EDTA (TAE) buffers for everyday electrophoresis.
