Division/Phylum: Ciliates/Ciliophora Class: Spirotrichea

Note: for strains where we have DNA barcodes we can be reasonably confident of identity, however for those not yet sequenced we rely on morphology and the original identification, usually made by the depositor. Although CCAP makes every effort to ensure the correct taxonomic identity of strains, we cannot guarantee that a strain is correctly identified at the species, genus or class levels. On this basis users are responsible for confirming the identity of the strain(s) they receive from us on arrival before starting experiments.
For strain taxonomy we generally use AlgaeBase for algae and Adl et al. (2019) for protists.

Notes The DP1, OK2 and LK2 strains of Euplotes crassus are all sexual derivatives of the original Luporini isolates, a series of at least 6 mass matings were performed over the course of past 35 years that resulted in this group of lines. The matings consisted of mixing all clonal cell strains available in the Lawrence Klobutcher Lab, Univ of Connecticut Health Ctr, at the time, along with a mixed culture, and then isolating sexual offspring; Name changed Oct22 taxonomic review.
