Simple surface plasmon resonance bio-sensor for the quantification of recombinant human epidermal growth factor (rhEGF) in expanded bed recovery

The conventional quantification assays used monitor the performance of protein downstream processing are typically not user friendly as it is laborious, time consuming and costly. At the same time, the emergence of multi-modal adsorbent, streamline Direct HST (1.8 g/cm3) to handle high ionic strengt...
