Among many variables that affect protein crystallization, such as growth condition, temperature, protein purity and concentration, the intrinsic characteristics of the protein is the most critical factor for protein crystallization.

• 蛋白质结晶受很多因素影响，蛋白质自身是结晶时最重要的变量，可以说，蛋白质的内在特性在某种程度上决定了其能否结晶以及所得晶体分辨率的高低。
