Figure 3
Variation in crystal scores for a single condition in a single plate. Protein Tt94, condition D7a (protein:precipitant ratio of 1:1). (a) Scored as 6 (needles); (b) scored as 8 [three-dimensional crystal(s)]; (c) scored as 4 (`bright spots'). All images are on the same scale, with the scale bar in (b) corresponding to 200 µm. The indicated region of (a) is enlarged, showing the needles. Note that they show a light-pipe effect, with the ends glowing brighter than the body of the needles.
