Distribution of agarose gel failures. Multiple amplification visualized as two or more bands on the gel accounted for 46.7% of the failed samples. Undesired amplification visualized as the wrong size bands on the gel accounted for 13.8% of the failed samples. Poor amplification visualized as a faint band on the gel was observed in 4.8% of the failed samples and no amplification took place in 34.7% of the failed samples.
