2013-03-19 12:22:12 - The DSM Biotechnology Centre, based in Delft, Netherlands, is taking advantage of Avacta Analytical’s Optim® 1000 micro-volume protein analysis instrument to characterise enzymes for use in the food industry.

Mark Stor, an associate scientist in the applied biochemistry department, explained: “Enzymes are sold on an activity basis, and that requires biochemical characterisation to establish what the enzyme looks like and how it behaves. We need to know the limitations of each enzyme to determine which applications it is most suitable for.”



“We saw the Optim at some laboratory fairs, and were interested in its ability to run temperature gradients and produce stability profiles. This is really important for us; stability is always an issue with enzymes. If an enzyme is produced at 30 °C, will it also work at 60 °C? We have to test the enzyme to establish its limits, looking at its activity at different temperatures and

in a range of formulations. To do this manually is extremely time consuming, but using the Optim it is possible to study 96 formulations in a day, obtaining a complete temperature profile that gives an indication of the most stable products. It is much quicker, and reduces the amount of work required. We can screen samples more quickly and, in the future, may even be able to replace lengthy shelf life studies.”
