摘要	We carried out a series of experiments to evaluate the efficiency of preserving DNA from porcelaneous foraminifera (Quinqueloculina spp.) and a second set to assess the effect of Rose Bengal staining on molecular processing. The first experimental setup assessed three methods of DNA preservation (air-drying, freezing with or without seawater, and Guanidine lysis buffer treatment with or without EDTA (Ethylenediaminetetraacetic acid)). Our study produced the following results: 1) there were no significant differences in DNA preservation when samples were air dried across a range of temperatures (20-120 degrees C); samples frozen at -20 degrees C appeared better preserved than at those frozen at -80 degrees C, and freezing without seawater appeared to produce better preservation than with seawater, though differences in freezing treatments were not significant (p>0.05); samples in Guanidine lysis buffer with EDTA and stored at -20 degrees C were well preserved (p<0.05); 2) sometimes, DNA was successfully extracted from samples stained with Rose Bengal. We recommend Guanidine lysis buffer with EDTA, stored at -20 degrees C for up to six weeks, as the best protocol for preservation of DNA from porcelaneous foraminifera.
