MAGNETIC BIOSENSOR FOR DETERMINATION OF ENZYMIC ACTIVITY

摘要

Magnetic sensors are very suitable for use in determination of enzymatic activity. In a preferred embodiment the invention relates to a method for determining activity of an enzyme in modification of substrate (2) to product (3), comprising binding substrate or a binding composition that may bind e.g. substrate or product, to the sensor surface. This enables easy detection of magnetic label that is linked to substrate, product or the binding composition.
