Summary
[edit]Description |
(a) A low magnification image immediately after co-injection of red negatively charged and green glycine-conjugated beads showing the injection site, marked with an oil droplet, appearing as a round yellow sphere. Overlap of red and green fluorescence produces a yellow image. (b) At 50 min after injection, the red carboxylated beads have progressed in the anterograde direction (to the right) while the green glycine-conjugated beads have made no progress. (c)–(e) An axon co-injected with red APP-C beads and green glycine beads and imaged for 100 frames at 4 s intervals at 40× magnification. (c) Red channel (left) first frame; (center) 50 frames superimposed; (right) all 100 frames superimposed. Note the progression of individual beads towards the right, anterograde, side of the injection site heading towards the presynaptic terminal. (d) Two images of the green channel from the same video sequence; (left) first frame; (center) 100 frames superimposed. Note the lack of significant movement of the green glycine beads. (e) Both red and green channels from 100 frames superimposed of the same video as in (c) and (d). (f) Single bead trajectories at high magnification from a set of superimposed frames showing movements of beads. |
