WebOct 14, 2024 · Absorbance of the sample can be calculated via Beer’s Law: (1.16.1) A = ε l c where A is the absorbance, ε is the molar absorptivity of the sample, l is the length of the cuvette used, and c is the concentration of the sample. [1] When the spectrophotometer produces the absorption graph, the molar absorptivity can then be calculated.

WebJun 15, 2009 · Absorbance at 280 nm by aromatic side chains is frequently used to monitor conformational changes in proteins as well as to determine protein concentrations. Absorbance at 230 nm ( A230) is also known to be sensitive to protein conformation [4], [5], [6], [7], [8], [9]. UV spectra of protein solutions usually show slopes, not peaks, at 230 nm.
