Crystals of the mouse major urinary protein (MUP) and rat alpha-2u globulin (AMG) have been grown from solutions of polyethylene glycol 3350 and CdCl2, respectively. The crystals differ both in their morphologies and space groups but have very similar unit cell sizes. AMG crystallized in P2(1) (a = 56.6 A, b = 103.8 A, c = 62.7 A, beta = 95.1 degrees) with four subunits/asymmetric unit, while MUP gave crystals in P4(1)2(1)2 or P4(3)2(1)2 (a = 57.3 A, c = 109.9 A) with one subunit/asymmetric unit. Both crystal forms diffract beyond 2.8 A resolution.
小鼠主要尿蛋白（MUP）和大鼠α-2u球蛋白（AMG）的晶体分别从聚乙二醇3350溶液和CdCl2溶液中生长出来。这些晶体在形态和空间群上都有所不同，但晶胞尺寸非常相似。AMG在P2(1)（a = 56.6 Å，b = 103.8 Å，c = 62.7 Å，β = 95.1°）中结晶，每个不对称单元有四个亚基，而MUP在P4(1)2(1)2或P4(3)2(1)2（a = 57.3 Å，c = 109.9 Å）中结晶，每个不对称单元有一个亚基。两种晶体形式的衍射分辨率均超过2.8 Å。
