Abstract: In PCR buffer, the DNA was recoveted from polyacrylamide gels by electroelution. The recovery efficiency was 0. 89± 0. 05. Added the PCR reagents,the DNA was directly amplified and the future analysis was performed. This method is easy, quick, inexpensive and highly efficient.

Key words: extracting DNA, PCR, acrylamidegels
