Figure 3
(a) Crystals of ConA labeled with the fluorescent probe PB and excited using a 400 nm blue LED without using an emission filter. (b) The well shown in (a) imaged using a 532 nm green laser diode and a 550 nm high-pass emission filter. (c) CR-labeled ConA crystals imaged using a 532 nm green laser diode and a 550 nm high-pass emission filter. (d) The well shown in (c) imaged under the light from a 400 nm blue LED without an emission filter. |
