How does a spectrophotometer work
WebNanoDrop spectrophotometers work on the principle of ultraviolet-visible spectrum (UV-Vis) absorbance. Nucleic acids absorb light with a peak at 260 nm. Purified proteins absorb light at a peak of 280 nm, while peptides and proteins that lack tryptophan and tyrosine residues absorb at a peak of 205 nm.
