UltraPure™ Phenol:Chloroform:Isoamyl Alcohol (25:24:1, v/v) is used in the purification of nucleic acids. This reagent consists of highly pure chloroform, isoamyl alcohol, and UltraPure™ Phenol saturated with Tris-HCl.
UltraPure Guanidine Hydrochloride is a strong protein denaturant. In a highly concentrated (5 to 6M) guanidine hydrochloride solution, many proteins unfold and separate into their constituent polypeptide chains.
UltraPure Dithiothreitol (DTT, Cleland's reagent), which reduces disulfides to their corresponding thiols, is used at low concentrations to stabilize enzymes containing free sulfhydryl groups.
Effectively screen colonies with X-Gal, an inert chromogenic substrate for beta-galactosidase which hydrolyzes X-Gal, forming an intense blue precipitate.
