Process Photometer for protein control Modelo: DCP007-UV
Proteins are large biological molecules comprised of one or multiple amino acids. Proteins in solution absorb ultraviolet light with an absorbance maximum at 280nm.
It is also possible to measure the purity of biomolecules by ratio of absorbance at 280nm and 260nm. The A260/A280 ratio provides an indication of protein contamination in nucleic acid isolates and less commonly, nucleic acid contamination in protein isolates.
