Abstract
Crystals of a chymotrypsin inhibitor from Erythrina caffra seeds have been grown out of lithium sulfate, by the hanging drop method of vapor diffusion. The crystals belong to the rhombohedral space group R32, with a = 67.2 A and alpha = 99.4 degrees, and diffract to 3 A resolution.
摘要
通过气相扩散悬滴法，从刺桐种子中提取的一种胰凝乳蛋白酶抑制剂晶体已在硫酸锂中生长出来。这些晶体属于菱面体空间群R32，a = 67.2 Å，α = 99.4°，衍射分辨率为3 Å。
