ABSTRACT:
We describe a process for the monitoring of contaminant removal during the purification process of a pharmaceutical product produced by a host cell, wherein at least two different samples taken during the purification process of the pharmaceutical product are incubated with at least one protein biochip array and contaminants in the samples bound to the protein biochip array are subsequently detected. Preferably samples are taken before the first purification step and after each subsequent purification step.
