Anomalous PCR products are often produced during the amplification of d(CA)n.d(TG)n sequences. Upon denaturing polyacrylamide gel electrophoresis, these products yield a ladder-like pattern that can complicate genotypic interpretation. We have developed two related techniques, referred to as two- and three-stage linear amplification (2-SLA and 3-SLA, respectively), which largely overcome this problem and yield readily interpretable banding patterns.
