Crystals of the indoloquinoline alkaloid cryptolepine complexed with the DNA fragment d(CCTAGG)(2) have been grown by the hanging-drop technique at 293 K using ammonium sulfate as the precipitating agent. Over a period of three weeks, yellow tapering bullet-shaped crystals grew to maximum dimensions of 0.2 x 0.1 x 0.1 mm. The crystals belong to space group P6(4), with unit-cell parameters a = b = 29.960, c = 39.64 A, alpha = beta = 90, gamma = 120 degrees, and diffract to 1.4 A.
通过悬滴法,以硫酸铵作为沉淀剂,在293 K下培养出了与DNA片段d(CCTAGG)(2)复合的吲哚喹啉生物碱隐丹参酮晶体。在三周的时间里,黄色的锥形子弹状晶体生长到最大尺寸为0.2×0.1×0.1毫米。这些晶体属于空间群P6(4),晶胞参数为a = b = 29.960,c = 39.64 Å,α = β = 90°,γ = 120°,衍射极限为1.4 Å。
