(A) One-photon photobleaching kinetics of GEVIs. Cultured neurons expressing ArcLight Q239 (n = 6 cells), ArcLight-MT (n = 6 cells), ASAP1 (n = 6 cells), ASAP2f (n = 7 cells), ASAP2s (n = 9 cells), Ace2N-4AA-mNeon (n = 7 cells), QuasAr2 (n = 11 cells), and Archer1 (n = 8 cells) are continuously illuminated with a mercury arc lamp.
(B) Time constants by 1-photon illumination (means ± SEMs).
(C) Two-photon photobleaching kinetics of GEVIs. Cultured neurons expressing ArcLight Q239 (n = 8 cells), ArcLight-MT (n = 7 cells), ASAP1 (n = 6 cells), ASAP2f (n = 9 cells), ASAP2s (n = 11 cells), and Ace2N-4AA-mNeon (n = 8 cells) are continuously scanned at 30 Hz.
(D) Time constants by 2-photon illumination (means ± SEMs).
