WebThese results were plotted in Figure 1. Figure 1 shows the absorbance increasing as the wavelength is increased until approximately 650 nm is reached; from this point, the absorbance pattern decreases rapidly. Therefore the peak wavelength for Methylene Blue is approximately 650 nm. Table 1 Figure 1: Absorbance vs. Wavelength 0.000 0.200 0.400 ...
Webspectrum appears as we would expect, the RIPA spectrum is quite distorted. The BSA sample suspended in PBS displays a peak at 280 nm, yet the BSA sample suspended in RIPA displays a trough at 280 nm. The difference in the absorbance at 280 nm between these two samples is approximately 88%.
