Product Information

BAN is molecular biology grade 4-bromoanisole for phase separation in the TRI Reagent® RT and RNAzol RT® procedures.


It replaces chloroform, the highly volatile compound commonly used for phase separation in the single-step method of total RNA isolation and in the TRI Reagent® method. Substituting BCP for chloroform moderately improves the quantity and quality of the isolated RNA (1).
