Coomassie Blue Description
Coomassie Blue is the assembly of the both triphenylmethane [C19H16] colorings,
which were used in the textile industry, but nowadays are getting in the
biochemistry by dying protein stains with blue hue. The more common Coomassie Blue dye
is the R-250, which combination consists of blue with red shade and the lucidity of the dye gel.
The other Coomassie G-250, whose "G" stands for Green, has pH more than 0. The difference
of the pH and the molecule structure makes the variety of Coomassie Blue. From red to green and
then to brilliant bright blue, just like the rainbow. Roughly said, Coomassie R-250 is more
responsive, while G-250 is more comfortable to be used.
