Case study of a semi-pure β-amylase extract

| Sponsored by Malvern Panalytical

The investigative power of multiple detectors. Here, we describe the analysis of a semi-purified protein mixture containing β-amylase. Step-by-step, we show how different properties of the proteins elicit a specific response in each detector and how coupling this data can be qualitatively and quantitatively evaluated.
