| Abstract: | To investigate the influential factors of different concentrations of some reagents and the comparability among the laboratories of RAPD. RAPD was carried out with different concentrations of reagents and three different amplified cyclers to amplify 11 strains of pathogenic vibrios. 11 strains of pathogenic vibvios were genotyped into 4 types, and could be easily repeated.The different concentrations of primer and 4 dNTP could influence the result of RAPD,but the fingerprints of RAPD produced respectively with 3 amplified cyclers were consistent. It is suggested that RAPD can be compared among the laboratories with the standard reagents. |
