Abstract
Routine genetic analysis of large numbers of individuals by polymerase chain reaction (PCR) using capillary electrophoresis is often restricted by the low throughput of standard protocols and the tedious sample preparation process. Here, we demonstrate that capillary electrophoresis with UV detection can be used in PCR‐based DNA analysis starting from clinical samples without purification or complicated sample manipulation. After PCR reaction using cheek cells, blood, or HIV‐1 gag DNA, the reaction mixtures were injected into a capillary array either on‐line or off‐line by base stacking. The use of multiplexed absorption detection and the elimination of any purification steps both before and after PCR reaction can potentially provide significant benefits compared to current methods for DNA analysis with regard to time, cost, and labor.
