What we can do for you

Our products


GECCO-enzymes and GECCO-cofactors are offered in a stable form (lyophilized)


GECCO-enzymes and GECCO-cofactors are offered as purified products


GECCO-enzymes and GECCO-cofactors are provided ready-to-use


GECCO offers a unique collection of cofactors.

One type of cofactors offered by GECCO are the deazaflavin cofactors.

The natural deazaflavin cofactors, F420 an FO, are notoriously difficult to produce and isolate and are currently only commercially available at GECCO Biotech.

GECCO also offers other flavin cofactor analogs and various enzymes that can be used for cofactor recycling which include:

  • a thermostable NADPH oxidase for recycling NADP+
  • a thermostable flavin reductase for recycling reduced FAD or FMN
  • a glucose-6-phosphate dehydrogenase to recycle F420
  • a thermostable catalase to recycle hydrogen peroxide into dioxygen and water
  • various dehydrogenase that can recycle NADH or NADPH
