    • A method for producing an ordered protein lattice, the method comprising: (a) providing a first component comprising a subunit of a homooligomeric protein assembly fused to a first subunit of a heterooligomeric protein assembly, and a second component comprising a second subunit of the heterooligomeric protein assembly, wherein the homooligomeric protein assembly and the heterooligomeric protein assembly are each symmetrical in two or three dimensions and share a rotational symmetry axis of the same order; (b) mixing said first monomer and said second monomer to produce a mixture; and (cl) (i) heating the mixture to a temperature about 2 °C to about 10 °C below the visible dissociation temperature; (ii) cooling the mixture by about 10 °C to about 20 °C; and (iii) repeating steps (i) and (ii) at least 10 times; or (c2) (i) heating the mixture to a temperature about 2°C to about 30°C or more below the visible dissociation temperature; and (ii) holding the mixture at a temperature about 2 °C to about 30 °C or more below the melt temperature, thereby producing an ordered protein lattice.
    • 一种用于产生有序蛋白质晶格的方法,所述方法包括:(a)提供第一组分,其包含融合到异寡聚体蛋白组合物的第一亚基的均低聚物蛋白组合物的亚基,第二组分包含异寡聚体的第二亚基 蛋白质组装体,其中均低聚体蛋白质组合物和异寡聚体蛋白质组合物在两个或三个维度上均对称,并且共享相同顺序的旋转对称轴; (b)混合所述第一单体和所述第二单体以产生混合物; 和(c1)(i)将混合物加热至低于可见解离温度约2℃至约10℃的温度; (ii)将混合物冷却约10℃至约20℃; 和(iii)重复步骤(i)和(ii)至少10次; 或(c2)(i)将混合物加热至低于可见解离温度约2℃至约30℃或更高的温度; 和(ii)将混合物保持在低于熔融温度约2℃至约30℃或更高的温度下,从而产生有序的蛋白质晶格。
