UCF.ME™ UltraNuclease GMP-grade

Details:

Description

UltraNuclease GMP-grade from 世界杯靠谱买球平台 is expressed and purified in Escherichia coli (E. coli) by genetically engineered and prepared under the GMP environments. It can reduce the viscosity of cell supernatant and cell lysate in scientific research, increase protein purification efficiency and enhance protein functional research. The product can also reduce host nucleic acid residues to pg-grade, improving the performance and safety of biological products of applications including virus purification, vaccine manufacturing, and protein/polysaccharide pharmaceutical manufacturing.

UltraNuclease from 世界杯靠谱买球平台 is provided in the form of a sterilized reagent, eluted in buffer (20 mM Tris-HCl pH 8.0, 2 mM MgCl2, 20 mM NaCl, 50% glycerin), with the appearance of a colorless, transparent liquid. This product is produced by GMP process requirements and provided in a liquid form.

Feature

  • Wide range of applications: degrade all forms of DNA and RNA 
  • High purity and activity: purity ≥ 99%; specific activity ≥ 1.5×106 U/mg
  • Strong adaptability: strong tolerance, adapt to a variety of reaction conditions
  • Comply with pharmacopeia: no animal origin; no antibiotics; lower endotoxin
  • Qualification: product gets the FDA DMF filling which can shorten the customers for new drug application
  • GMP-grade manufacturing: strict standards to meet the needs of large-scale use for research to manufacture

Application

  • Purification of viral vaccines, viral vectors for the vaccine, and oncolytic viruses, removing DNA/RNA from proteins and other biologicals
  • Reduction of viscosity caused by nucleic acids
  • Sample preparation in electrophoresis and chromatography
  • Prevention of cell clumping
