Description
Summary:A specific DNA extraction method for sea anemones is described in which extraction of total DNA from eight species of sea anemones and one species of corallimorpharian was achieved by changing the standard extraction protocols. DNA extraction from sea anemone tissue is made more difficult both by the tissue consistency and the presence of symbiotic zooxanthellae. The technique described here is an efficient way to avoid problems of DNA contamination and obtain large amounts of purified and integral DNA which can be used in different kinds of molecular analyses. Descreve-se um método específico de extração de DNA para anêmonas-do-mar no qual o DNA total de oito espécies de anêmonas-do-mar e de uma espécie de Corallimorpharia foi obtido através de modificações de protocolos padrões de extração. A extração do DNA de anêmonas-do-mar tem sido dificultada pela consistência rígida do tecido e pela presença de zooxantelas simbiontes. A técnica descrita aqui é um meio eficaz para evitar problemas de contaminação de DNA e de obtenção de grandes quantidades de DNA íntegro, o qual pode ser usado em diferentes tipos de análises moleculares.
