T4 DNA Ligase Competitor Study - Nuclease Contamination
T4 DNA Ligase from multiple suppliers was tested in reactions containing a fluorescent labeled single stranded, double stranded blunt, 3'overhang or 5' overhang containing oligonucleotides. The percent degradation by contaminating nucleases is determined by capillary electrophoresis and peak analysis. The resolution is at the single nucleotide level.
An E. coli strain that carries the cloned T4 DNA Ligase gene.
