How to determine the concentration and purity of a DNA sample Impurities in DNA may lead to inaccurate measurement of DNA concentration and could potentially inhibit subsequent labelling reactions. One of the common methods of measuring nucleic acid purity and concentration are spectrophotometric absorbance of a sample at 260nm compared to the value measured at 280nm .

Determination of DNA concentration byThis is done mostly to conserve DNA. Isolating and purifying DNA takes time, and since the cuvettes are not sterile, you don't want to waste 2 ml of your DNA on a concentration determination! So, you use small volumes (520 ml), and given the constraints of the equipment, this means you have no choice but to dilute the DNA. Also, absorbance values above 2.0 are not very reliable, thus measurements in this range are likely to be very rough estimates.
