For enzymatic DNA removal in bioprocessing!

  • Drug Master File for DENARASE approved by FDA

    c-LEcta has reached a major milestone with the successful submission of a Drug Master file at the US FDA for DENARASE®.

    This registration will reduce the regulatory work for DENARASE® customers who are looking for a US-market approval of a therapeutical product, such as vaccines and advanced therapy medicinal products. The Master File demonstrates the suitable quality of DENARASE® for use in pharmaceutical products.

    For more detailed information how to use the DMF File please request the US FDA DMF Support for DENARASE® GMP-grade.


How it works

DENARASE® specifically hydrolyzes the phosphodiester bonds between nucleotides leaving smaller fragments of around 5 ­– 8 base pairs. The enzyme is active on all forms of nucleic acids including single-stranded, double-stranded, linear, circular or supercoiled. Best results are obtained when the enzyme is added before the release of DNA.

Production of DENARASE

DENARASE® has been developed for use in commercial manufacturing processes of biologicals and complies with EU GMP regulations. The patented production process uses a gram-positive Bacillus sp. production host, which minimizes the risks of endotoxins in the product. No antibiotics, materials with TSE/BSE risk or raw materials of animal origin are employed in the manufacture of the product.
