The major mutagenic base lesion in DNA caused by exposure to reactive oxygen species is 8-hydroxyguanine or 7, 8-dihydro-8-oxoguanine (8-OH-G). Products of the human MMH/OGG1 gene are known to catalyze in vitro the reactions repairing this DNA lesion. To analyze the function of Mmh in vivo, we generated a mouse ... More

Improved Plasmodium falciparum cDNA expression libraries were constructed by combining mRNA oligo-capping with in vitro recombination and directional cloning of cDNA inserts into a plasmid vector that expresses sequences as thioredoxin fusion proteins. A novel procedure has also been developed for the rapid identification of seropositive clones on high-density filters, ... More
