Deletion mutagenesis of large areas in Plasmodium falciparum genes: a comparative study

Malaria Journal

Table 1 Primers used for the various mutagenic protocols. The Bam HI restriction sites for primer pairs P3 and P4 are underlined. The P3 primer pair was used with and without Bam HI restriction digestion for the RE-mediated inverse PCR and inverse PCR methods, respectively.

* The Tm's were calculated according to the Stratagene formula: 81.5 + 0.41(%GC) - 675/N) or for primer pairs P3 and P4 with the Rychlik et al. formula: 69.3 + 0.41(%GC) - (650/N) [26] as indicated in parentheses.
↓ indicates where the deletions are made with the overlapping primers.
