Initial in surfo crystallization hits with LysP. In (a) and (b) the precipitant solution consisted of 50 mM magnesium acetate, 26%(v/v) PEG 350 MME, 0.1 M MES pH 5.4 in the presence of 5 mM
l-lysine. The crystals in (c) and (d) were grown using precipitant consisting of 0.1 M MgCl2, 0.1 M NaCl, 33%(v/v) PEG 400, 0.1 M Tris–HCl pH 8.5 in the presence of 5 mM
l-lysine. Images were recorded under visible light (a, c) and UV light (b, d) using a Korima UV microscrope.
