Description

Description générale

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.

Application

• Can be used directly in cell medium or harvested supernatant without buffer adjustments
• Ideal for DNA removal directly in mammalian cell media

Caractéristiques et avantages

• Active at physiological conditions
• Endotoxin tested Animal origin free without buffer adjustments.

Définition de l'unité

One unit is defined as the amount of enzyme that causes a ΔA260 = 1.0 in 30 minutes at 37 °C in 25 mM Tris-HCl pH 7.6 (@25 °C), 2.5 mM MgCl₂, 150 mM NaCl, and 50 μg/ml calf thymus DNA. 25 mM Tris-HCl pH 7.6 (@25 °C), 2.5 mM MgCl₂, 150 mM NaCl, and 50 μg/ml calf thymus DNA
