title: Isolation of alveolar plates from Coleps hirtus.
abstract: In the ciliate Coleps hirtus, the alveoli contain rigid alveolar plates that are almost unstudied so far. Neither the exact composition nor the genesis and function are known. A necessary step to study the alveolar plates is to isolate these structures in an adequate amount. Therefore, culture conditions of C. hirtus were optimized to obtain an axenic and dense long-time culture. The protocol we developed to isolate C. hirtus alveolar plates is presented and clean alveolar plates were documented via scanning electron microscopy. The described procedure delivers alveolar plates of very good structure and integrity with preserved filigree details in sufficient amount. They can be analysed via a range of different material and biological characterisations. Since there are indications of a mineral phase within the alveolar plates, the presented results will allow to study C. hirtus alveolar plates also in the context of biomineralisation.
