On error rates of Mutazyme

On a previous jocular post about the 'not for diagnostic purposes' tag on Mutazyme I mention the mutational rate of Mutazyme II. The exact mutations per kb per doubling is never mentioned in the manual, but can be extrapolated. (see also part III: Mutazyme and Manganese)

The heteroduplicity of error prone PCR plasmids

A mix of wt and

mutant...

In an error prone PCR the ep-aDNA is ligated onto a plasmid backbone and transformed. When assessing the diversity from a naïve plasmid pool, something odd is seen: some bases are mutated but not to saturation. This is often just dismissed or simply overlooked, but I suspect it is actually something interesting...
