GENIUS™ Nuclease, premium grade

Product Details

GENIUS™ Nuclease, premium grade is a tag-free recombinant form of Serratia marcescens extracellular endonuclease produced in Escherichia coli using a proprietary process at ACRObiosystems. GMP GENIUS™Nuclease performs optimally at low and physiological salt concentrations (0-200 mM NaCl). The product is a homodimer with monomer molecular masses of about 30 kDa. The enzyme is a non-specific nuclease with high specific activity, degrading single- and double-stranded nucleic acids in any form (single stranded, double stranded, linear, circular, and supercoiled). It hydrolyzes internal phosphodiester bonds present between the nucleotides to 5’- phosphorylated oligonucleotides of 3-5 bases in length.

Features and Advantages

1. GENIUS™ Nuclease, premium grade is designed for preclinical stage, has more comprehensive QC testing (such as HCP and so on) and tighter specifications based on the following GENIUS features.
2. GENIUS™ Nuclease, premium grade has the same activity and performance with GMP Grade Nuclease, which enables a seamless transition from preclinical development to clinical phases. By using GENIUS™ Nuclease, premium grade in your development phase you can easily transit into clinical and commercial phases and avoid needing to amend your manufacturing process and undertake comparability studies.
3. Generally usable: Generally usable for removing all forms of DNA and RNA from biological products, reducing viscosity and preventing cell clumping
4. Efficient: Efficient reaction, rapid degradation, reduce processing time
5. Native: Native structure, tag free, the enzyme activity is more guaranteed
6. Ideal: Ideal for DNA and RNA clearance
7. Ultra pure: High purity and activit
8. Specific: Specific nuclease, no protease activity

Application

Elimination of nucleic acids from biologics, suitable for samples with 0-200 mM salt in presence of 2-10 mM Mg++
• viral vaccine development process
• viral vector development process for cell and gene therapy (CGT)
• Other biologics development processes

Operating Conditions

GENIUS™ Nuclease, premium grade is functional between pH 6 and 10 (optimal at pH8 - 8.5) , and from 0°C to 42 °C (optimal at 35 °C - 42 °C). Mg2+ (1-2 mM) is required for enzyme activity.1 mM EDTA reduced the activity by 30% in the presence of 1 mM MgCl2; 0.1 M EDTA eliminated all enzyme activity. In the presence of 1 mM MgCl2, enzyme levels were reduced 75% by 0.1 M CaCl2 or 1 M NaCl. Under standard assay conditions, 1 mM iodoacetate had no effect on the enzymatic rate, whereas 1 mM mercaptoethanol and maleic acid reduced the activity by only 5 to 10%. 10 mM p- Chloromercurybenzoate completely inactivates the enzyme, while 0.64 M beta-mercaptoethanol in the presence of 2 M urea causes only partial inactivation of the enzyme. 4 or 7 M Urea increases the enzyme activity.
