Glutatión S-transferasas (GST) son enzimas de desintoxicación implicadas en el metabolismo de numerosos fármacos quimioterápticos. La sobreexpresión de los GST está correlacionada con la resistencia a la quimioterapia contra el cáncer. Una manera de contrarrestar este fenotipo es usar inhibidores. Este protocolo describe un método que utiliza un ensayo espectrofotométrico para detectar posibles inhibidores del GST.
