Hen egg-white avidin has been crystallized at pH 5.7 from ammonium sulfate solutions. The crystals belong to the tetragonal space group P4(2)2(1)2, with unit cell edges a = b = 79.6 A, c = 84.3 A. Assuming a molecular weight of 15,600 per avidin monomer, this crystal form is compatible with the presence of a dimer in the asymmetric unit, and is suitable for a crystallographic structural investigation at high resolution.
鸡蛋清抗生物素蛋白已在pH 5.7的条件下从硫酸铵溶液中结晶出来。这些晶体属于四方晶系空间群P4(2)2(1)2，晶胞参数a = b = 79.6 Å，c = 84.3 Å。假设每个抗生物素蛋白单体的分子量为15,600，这种晶体形式与不对称单元中存在二聚体相符合，并且适合进行高分辨率的晶体学结构研究。
