Nanodrop says the 260/280 value of my DNA sample is around 2.1 and the 260/230 value is 2.3 and 2.4. Does it mean my sample is pure enough or contaminated?
Dear Murugadass,
Oliver Krohn has given the correct document. For DNA it should be 1.8 and 2.0 for RNA in 260/280. The value of 260/230 should be more than 260/280.
Hello Oliver,
Yeah, i too come across this is pdf. But here my value is 2.1 which is not mentioned anywhere in the doc. what does it mean? Does it pure or contaminated?
Check your DNA on a gel for purity/contamination. I think it is a better way than (only) Nanodrop. Good luck!
Even the procedure look easy, should take care if the concentration of genomic is very high. Can cause problem during reading in optic fiber tube.
