Proteins containing the appropriate amino acids are absorbent to light on the UV-spectrum, specifically light that has peak wavelengths of 260 – 280 nanometers (nm). This makes it simple to analyze ...
This article shows how the absorbance maxima of Ponceau-S is determined over a wavelength range of 220nm to 800nm using the Eppendorf BioSpectromenter ®. The methods of analysis using this ...
A necessary step in the preparation of biomolecules for downstream applications is determining their concentration by photometric methods, once the nucleic acids or proteins are isolated. Biomolecules ...
