From: Preparation of cross-linked hen-egg white lysozyme crystals free of cracks

Visual analysis chart of the influence of various factors on crack ratio of crystals in the orthogonal experiment.
(a) Temperature; (b) Glutaraldehyde concentration; (c) Cross-linking time; (d) Solution pH; (e) Growth time. Note: Every column in the figure represents the averaged crack ratio of four combinations in the orthogonal array, and there is no error bar.
