DNA purity

Postby JackBean » Fri Dec 02, 2011 7:01 pm

is it true, that when the ratio ABS260/ABS280 > 1.9, the DNA is not pure, but impure with RNA or some organic compounds?

Cis or trans? That's what matters.

to the best of my knowledge, pure DNA preparation have expected ABS260/ABS280 ratio between 1.8 and 2.0.
AHH, Gravity! Such a cold cruel mistress.
