利用电子显微镜和蔗糖密度梯度中活性组分的粒子计数研究了从海洋鞭毛藻Gonyaulax polydra中提取的生物发光粒子（‘闪烁’）的物理特性。膜状结构大量存在于纯化的组分中，而相对于活性，鸟嘌呤晶体的数量减少，而鸟嘌呤晶体以前被认为是生物发光结构。讨论了这些发现对体内闪烁的意义。
The physical identity of the bioluminescent particles (‘scintillons’) extracted from the marine dinoflagellate Gonyaulax polyedra was investigated by electron microscopy and particle counts of the active fractions from sucrose density gradients. Membranous structures are abundantly present in purified fractions, while there is a decrease, relative to activity, in the numbers of guanine crystals, which had previously been implicated as bioluminescent structures. The significance of these findings with respect to the in vivo scintillon is discussed.
