I couldn’t believe how pretty this is.  I used an old technique called ‘thin layer chromatography’ because I need to separate citrate from the by-products of an enzyme reaction.  I stained the chromatography plate by spritzing it with bromocresol green, and enhancing the contrast with ammonia fumes.  The yellow spots are citric acid, succinate, malate, and oxaloacetate.
