It is difficult to keep biological samples collected from the field fresh and transport safely to laboratory for RAPD analyses. In this study, the DNA templates extracted from muscles kept in different fixatives for more than 70 days in summer were compared in RAPD analyses and the DNA extracted from frozen muscles of same individuals was used as control. The result suggested that the muscle kept in 70% ethanol with 50mmol/L EDTA was quite good for template DNA extraction and RAPD reaction. At least, the sa...
