Jena Bioscience Gel Loading Buffers are formulated to facilitate loading of DNA containing samples into the wells of agarose and polyacrylamide gels. The buffers contain tracking dyes as indicator for DNA fragment migration. In addition, they contain glycerol to add density and EDTA to inhibit nuclease activities.
The buffers are optimized for loading of DNA fragments in a size range of:

Cat. No.Gel Loading Bufferfragment size
PCR-254-blBlue Gel Loading Bufferlarger than 500 bp
PCR-254-grGreen Gel Loading Bufferfrom 100 to 2000 bp
PCR-254-orOrange Gel Loading Buffersmaller than 500 bp

6x Gel Loading Buffer:
60 mM Tris-HCl (pH 7.5), 60 mM EDTA, 50 % (w/v) Glycerol, bromophenol blue (blue buffer), xylene cyanol FF (blue and green buffer), orange G (orange buffer) and tartrazine (green buffer)
