PCR amplification of P. falciparum cDNA inserts cloned into the T7Select10-3b vector. All fragments include 107 bp of vector sequence. Lanes 2–12 depict amplified DNA from selected phage recombinants. Lane 1 is a 100 bp DNA ladder (Promega, USA). PCR products were evaluated using 1% agarose gel electrophoresis and ethidium bromide staining.
