Available Substrates

We specialize in two different and unique ways of measuring enzyme activity:
on purified biopolymer substrates and on complex biomaterial substrates.
We produce enzyme substrates from our own stock or from customers’ own material.

Purified Biopolymer Substrates

Purified biopolymer substrates are substrates synthesized from pure polysaccharides and proteins. They are chemically dyed and cross-linked rendering them insoluble and chromogenic. These substrates can be made in a minimum of four colors (red, yellow, green, and blue). They are optimized for application in a high-throughput format for quick, easy, and cost-effective handling, and they have a wide temperature and pH tolerance.

Complex Biomaterial Substrates

These substrates are synthesized from the complex biological material and maintain a high level of similarity with the original material, chemically and physically. Hence, they provide:

  • Information about substrate availability within the complex polymer mixtures typically encountered by enzymes in industrial context.
  • A highly realistic impression of enzyme activity towards the complex biomass substrates.
