Potassium Hydroxide 3% is used to differentiate gram-positive and gram-negative microorganisms. Gram-negative cell walls are broken down by 3% KOH and it releases viscoid chromosomal material which causes suspension to become thick and stringy. This reaction characterizes the gram-negative bacteria.Ready to use: Convenience of prepared reagentEasy to interpret: Stringy, viscous material pulled up from suspension within first 30 seconds is easy to interpret.Not all products are available for sale in all territories. Please inquire.Remel™ and Oxoid™ products are now part of the Thermo Scientific brand.
