Infrared absorption spectra in the amide-I region of poly-l-lysine (purple) that was slowly dried in the presence or absence of various proteins, including LEA proteins (GmPM1 only, black; GmPM1 with poly-l-lysine, blue; GmPM28 only, green; GmPM28 with poly-l-lysine, yellow) and lysozyme (lysozyme only, orange; lysozyme with poly-l-lysine, red).
