Length distribution analysis of fibrils imaged using TEM.

<p>Fibril lengths were measured in the absence of cosolutes, (<b>A</b>) at <i>t</i> = 0 (average length, as calculated directly from measurements, 263±114 nm), (<b>B</b>) at <i>t</i> = 500 min, (average length 458±146 nm); and in presence of 30% (w/w) sorbitol, (<b>C</b>) at <i>t</i> = 0 min (average length is 142±64 nm), (<b>D</b>) at <i>t</i> = 500 min (average length 265±95 nm). Errors in average length are standard deviation of length measurements.
