A sample spectrum (Figure 3) shows that SDS does not have a strong signal in the amide I region and explains why SDS does not interfere with IR-based protein quantitation.

The IRMPD spectra of each 5/3 conformer are given in Fig. 3c.All the spectra show strong amide II and I features in the 1,500–1,580 cm −1 and 1,600–1,700 cm −1 region, respectively, and ...

The spectrum shows a better signal for the Amide I that is similar to the FTIR spectrum of the bacteria culture (Figure 3 in green). The intensity of the PHB in that case has decreased compared to the ...

Right: O-PTIR spectra from the IR image (left), with spectra on (#1) and off (#2) the beta protein structure. Spectral discrepancies demonstrate changes in the amide I band, characteristic of ...
