The antenna complexes from Rps. cryptolactis have been isolated and purified. Rps. cryptolactis contains two types of variable antenna complex, B800-850 and B800-820 as well as the 'core' B875 antenna complex. The variable antenna complexes contain more than two types of antenna apoprotein, and have a Bchla:carotenoid ratio of ∼2:1. They can both be crystallised, but the B800-820 complex is the easiest with which to get relatively large single 3-D crystals (up to 0.5 mm in each dimension).
已分离并纯化了来自 Rps. cryptolactis 的天线复合物。Rps. cryptolactis 包含两种类型的可变天线复合物，B800-850 和 B800-820 以及“核心”B875 天线复合物。可变天线复合物含有两种以上类型的天线脱辅基蛋白，并且具有 Bchla：类胡萝卜素的比例约为 2：1。它们都可以结晶，但 B800-820 复合物是最容易获得相对较大的单个 3-D 晶体（每个维度可达 0.5 毫米）的复合物。
