Endonuclease III (Nth)

Application Features

• Single cell gel electrophoresis (Comet assay) (3,4,5)
• Alkaline elution (6)
• Alkaline unwinding (7)

1. Effective with M0268S/L spec V2, NEB has updated the product specification as follows:
2. Protein Purity Assay (SDS-PAGE):  Endonuclease III (Nth) is ≥95% pure as determined by SDS PAGE analysis using Coomassie Blue detection.
3. qPCR DNA Contamination (E. coli Genomic):  A minimum of 1 μl of Endonuclease III (Nth) is screened for the presence of E. coli genomic DNA using SYBR^® Green qPCR with primers specific for the E. coli 16S rRNA locus.  Results are quantified using a standard curve generated from purified E. coli genomic DNA. The measured level of E. coli genomic DNA contamination is ≤1 E. coli genome.
4. Endonuclease Activity (Nicking): Removed to align with standard quality control testing for product portfolio.
