Bromocresol Green (BCG) is a pH sensitive triphenylmethane dye useful in a variety of colorimetric detection technologies. BCG is used as a tracking dye for DNA agarose gel electrophoresis, in protein determinations and in charge-transfer complexation processes. In TLC BCG is used for visualisation of the compounds with functional groups whose pKa is below 5.0.

Nutrition can affect the hypothalamus-pituitary-adrenal axis. We hypothesized that early administration of parenteral nutrition (PN) during critical illness reduces plasma ACTH and cortisol concentrations and thereby increases the use of corticosteroids. This is a preplanned substudy of a randomized controlled...
