*Does anyone knows what is the PEG (Polyethilene glycol) absorbance ratios?
I recently used PEG to make a PCR purification and the
spectrophotometry tells me that it** was ok (120 ng/ul . Good 260 measure
and low 280,230 and 320) but **when I loaded the PCR purification into a 1%
Agarose gel it shows me nothing.
I suspect PEG contamination into my sample.
