Avidin was crystallized in various forms from 3m-ammonium sulphate or sodium phosphate at pH5.2. X-ray-crystallographic analysis of crystals from phosphate showed them to be orthorhombic, space group C222, containing two molecules per unit cell and with a single subunit as the asymmetric unit. The formation of the complex with biotin did not affect the morphology of the crystals.

抗生物素蛋白在pH5.2的3m硫酸铵或磷酸钠中以多种形式结晶。对磷酸盐结晶进行的X射线晶体学分析表明，它们为正交晶系，空间群为C222，每个晶胞包含两个分子，且以单个亚基作为不对称单元。与生物素形成复合物并不影响晶体的形态。
