Guanidine Thiocyanate is an ultrapure, molecular biology grade reagent. It is free of detectable nuclease and protease activity and is a strong protein denaturant, as both the guanidinium cation and the thiocyanate anion are chaotropic agents.
Stabilize enzymes and other proteins which possess free sulfhydryl groups with DTT, shown to restore activity lost by oxidation of these groups in vitro.
Detect expression of the URA3 gene, which encodes orotine-5'-monophosphate (OMP) dicarboxylase with Thermo Scientific™ 5-Fluoroorotic Acid, used in yeast molecular genetics.
