Meaning of "standard reactions" in a DNA extraction procedure description
Is this PCR or just DNA extraction and if so, what is the source material?
If it is just DNA extraction, maybe the standard reaction means to extract some given standard sample DNA (CHO cell genomic DNA?) to optimise the yield and reaction conditions.
You would ideally use these same reaction conditions to extract other genomic DNAs.
Also, is the CHO genomic DNA included in the kit?
