Live-cell SRS imaging of mHtt-97Q-GFP aggregates with Gln-d5 labelling. a SRS imaging of mHtt aggregates (arrowheaded, 2167 cm−1, C–D on), validated by fluorescence imaging through GFP (Fluorescence). Off-resonance image at 2035 cm−1 shows no signal. b Live-cell SRS images for an mHtt-97Q-GFP aggregate (arrowheaded) at Gln-d5 (2167 cm−1), CH3 (2940 cm−1), and amide I (1664 cm−1) channels on the same set of HeLa cells. c SRS imaging of an mHtt-97Q-GFP aggregate at 2143 cm−1 by leucine-d10 (Leu-d10) labelling. d Average Sagg/Bcell from SRS images of C–D with Gln-d5 labelling (5.75 ± 1.03, n = 13); amide I (2.15 ± 0.34, n = 4); CH3 (1.66 ± 0.14, n = 10); and C–D with Leu-d10 labelling (2.45 ± 0.33, n = 10). Error bar SD.
