一般描述
This Salt Active Nuclease (SAN) has been developed to offer the optimal solution for removal of nucleic acids at the near-physiological conditions used in many bioprocessing and biomanufacturing workflows. This novel, nonspecific endonuclease is active over a broad pH range and displays optimum activity at salt concentrations around 175 mM. It is recombinantly expressed in Pichia pastoris.
应用
- Can be used directly in cell medium or harvested supernatant without buffer adjustments
- Ideal for DNA removal directly in mammalian cell media
特点和优势
- Active at physiological conditions
- Endotoxin tested Animal origin free without buffer adjustments.
