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 ...

When a molecule of tryptophan absorbs ultraviolet light, it glows faintly as it releases energy at a lower frequency. This effect, called fluorescence, is well known. But something extraordinary ...

As Raman technology has advanced more challenging applications have been explored, where high fluorescence and low concentration of samples are present. Monoclonal antibodies and antibody fragments ...
