Product nameBromophenol blue, Tracking dye
DescriptionTracking dye for nucleic acid or protein electrophoresis.
- Bromophenol Blue (BPB)
- Bromphenol Blue Sultone Form
pH indicator (pH 3.0 (yellow) - 4.6 (blue)). Tracking dye in DNA, RNA (agarose) and protein (polyacrylamide) gel electrophoresis. Migrates at approximately the same rate as 300-500bp DNA in agarose gel and at the buffer front in protein polyacrylamide gels.
Storage instructionsStore at Room Temperature. Store under desiccating conditions. The product can be stored for up to 12 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
