DNA Concentration Guidelines

DNA Concentration Guidelines:

We recommend that you not only UV spec your samples but also run them on a gel to double check your concentrations.

PCR products: Please supply us with 2ng/uL per 100bp of PCR product. (Example: A 700bp PCR product would be submitted at 14ng/uL).

Plasmids: Because concentration measures the total amount of DNA, without accounting for the size, as the plasmid size increases so must your DNA concentration. A general guideline for double stranded plasmid templates are as follows:

Template Size: Concentration:

Double stranded 3kb

100-200ng/uL

Double stranded 4kb

200-250ng/uL

Double stranded 5kb

250-300ng/uL

Double stranded 6kb

300-400ng/uL

Double stranded 7kb

400-500ng/uL

Double stranded 8kb

500-700ng/uL

Double stranded 9kb

700-800ng/uL

Double stranded 10kb

800ng/uL-1ug/uL

Double stranded >10kb

1ug/uL++
