DENARASE® High Salt

DENARASE® High Salt is an engineered version of the wild-type Serratia marcescens endonuclease. By introducing a few amino acid substitutions, the enzyme was optimized for salt tolerance. This allows the enzyme to retain its activity at higher salt concentrations without losing specificity for nucleic acids. DENARASE® High Salt exhibits higher DNA removal activity across a broader range of salt concentrations and pH levels. These features provide greater flexibility in bioprocessing and enable seamless integration into existing workflows.

Why High Salt?

Salt concentrations between 200 mM and 400 mM can improve the solubility of viral vectors and impurities and thereby reduce the formation of aggregates. In addition, non-aggregated DNA is more accessible for endonucleases, which further contributes to a more efficient process.  

Challenge: Standard endonucleases for DNA removal are inhibited by salt concentrations >200mM

Why choose DENARASE® High Salt?

DENARASE® High Salt is the first engineered S. marcescens endonuclease that keeps its activity also at higher salt concentrations. As the engineered enzyme also remains active over a broader pH range, DENARASE® High Salt offers more flexibility for process developers to optimize the purification process of viral vectors.

Benefits of DENARASE® High Salt

    The one-for-all Serratia marcescens ELISA Kit
DENARASE-High-Salt

Best performance from low to high salt! 

Our DENARASE® enzyme portfolio allows for efficient DNA removal across a broad salt spectrum and different pH levels, allowing you to choose the enzyme that best fits your process conditions. At low to physiological salt conditions, the standard DENARASE® exhibits peak performance and continues to be the most economical solution.  For processes that benefit from salt addition, DENARASE® High Salt offers the greatest flexibility and cost-efficiency.

DENARASE vs DENARASE High Salt

Recommended conditions: 

DENARASE®

  • pH: 7.4-9

  • Salt: 0-150 mM

DENARASE® High Salt

  • pH: 7.4-9
  • Salt: 0-500 mM
  •  

Engineered innovation that adapts to your process!

DENARASE® High Salt shows a high DNA removal activity across a wide range of salt concentrations, outperforming other salt-active endonucleases (Salt-E). Especially at pH 7.4 the activity of DENARASE® High Salt is significantly higher than its competitors.

c-LEcta Salt Performance Test. Measured DNA removal activities [UnitTest/μL] were normalized to the applied nuclease units as specified in the manufacturer’s CoAs [UnitCoA/μL] and are depicted as [UnitTest/UnitCoA].

Avoid additional salt & pH adjustments!

DENARASE® High Salt shows a high activity at salt concentrations that are commonly applied during the harvest step. This avoids the need for salt and pH adjustments to increase endonuclease activity, as required for some of the other marketed salt active enzymes. Maximize your bioreactor capacity – without reserving space for buffer and salt additions.
