Biotin absorption spectrum
WebThe absorbance spectra of most protein buffers and components show some absorbance in the lower UV region (fig. 1), likely caused by various salts present in the buffer. This absorbance, however, typically decreases to baseline by ~230 nm. These buffers therefore do not affect the accuracy of A280 quantification.
