Resumo

Separation of bacteria from duodenal digesta prior to storage (−25 °C) resulted in 17 and 27% loss of RNA at 1 and 2 weeks, respectively. Storage of total digesta, with bacterial separation immediately prior to analysis, prevented loss of RNA. Purine base concentrations were not influenced by storage. However, removal of free purine base in digesta prior to analysis is recommended. Key words: Nucleic acids, freeze-storage, bacteria, duodenal digesta
