Additional remarks genetic modification | Unsuccessful attempts to disrupt the gene indicate that this gene is essential for asexual blood stage growth/multiplication.
Fragments of the 3’ and 5’ UTR were amplified from gDNA using gene-specific primers. First, 3’ fragments were cloned into the pBAT vector, following restriction digestion with HindIII and KpnI to generate an intermediate construct (pHEME-im). Then, the 5’ UTR fragment was digested with SacII and EcoRV and cloned into the respective SacII- and PvuII-linearized pHEME-im construct, thus removing the mCherry-3xMyc tag. Finally, the pHEME-ko vector was linearized with ScaI and SalI before transfection into P. berghei strain ANKA (wt) parasites. |
