Abstract

Abstract

The material for DNA extraction of sea cucumber which involve refrigeration may not always be convenient because of certain conditions that cannot be achieved. So, we tried out drying the sea cucumber body wall. A comparison is made with traditional ethanol preservation and a modern molecular method in 3 different sampling methods: storage in 96 % Ethanol under refrigeration; storage in RNAlater (Quiagen) under refrigeration and drying in excess silica gel at ambient temperature. The result clearly shows that there is at least some DNA in every samples. Even though it is not an optimial method, silica gel drying can be used for sea cucumber DNA sampling.
