Recombinant Microbial Catalase (Lyophilized Powder)

Novel high-performance catalase purified from a psychrotolerant bacterial origin, produced recombinantly in non-pathogenic strain of E. coli.


  • Recombinant - fast and sustainable production in a non-pathogenic strain of E. coli
  • Microbial origin - free from any animal or plant related contamination
  • Extremely reliable - maintains over 80% of its activity from 20-70C
  • High Thermal Stability - maintains over 50% of its activity for 7 hours at 50C

Catalase is an enzyme that catalyzes the transformation of hydrogen peroxide into water and oxygen. This enzyme functions as a natural antioxidant protecting the cell against oxidative damage. This enzyme finds applications in Research and Clinical Chemistry. It also finds diverse industrial applications in textiles, waste treatment, cosmetics and as a disinfectant agent.
