Absorbance and fluorescence analysis are distinct yet complementary techniques used to detect and quantify analytes of interest in a sample. Measuring the absorbance of ultraviolet and visible (UV-Vis) light at specific wavelengths is one of the most established methods of quantitating biomolecules. Fluorescence analysis, meanwhile, has long been used to measure the emission spectra of

Measuring the UV-light absorption of proteins is the most straightforward method of microvolume protein analysis for concentration and purity. The aromatic amino acids and residues of many proteins exhibit strong ultraviolet absorption with a peak at 280nm.  The amount of light absorbed is proportional to the concentration of the sample. Using the Beer-Lambert equation, it

Ultraviolet-visible (UV-Vis) spectrophotometry is a technique used to measure light absorbance across the ultraviolet and visible ranges of the electromagnetic spectrum. When incident light strikes matter it can either be absorbed, reflected, or transmitted. The absorbance of radiation in the UV-Vis range causes atomic excitation, which refers to the transition of molecules from a low-energy

Fluorometers are used for precise quantitation of biological molecules including nucleic acids and proteins in microliter (μl) samples. They can measure the concentration of double- and single-stranded DNA (dsDNA and ssDNA), ribonucleic acid (RNA), and proteins in solution with demonstrable applications in a range of biochemical fields.
