After confirmation of correct
integration, genomic DNA from wild type and transgenic parasites was digested with BsmI
and the fragments were separated on a 0.8% agarose gel, blotted onto a nylon membrane, and
probed with a PCR fragment homologous to the P. berghei genomic cyc3 sequence cloned in
the p277 vector, using the Amersham ECL Direct Nucleic Acid Labelling and Detection kit
