Figure 5From: Putative DNA G-quadruplex formation within the promoters of Plasmodium falciparum var genesThermal denaturation curves (heating) of putative G-quadruplex sequences (PQS) from the upstream B regions of var genes in 150 mM potassium cation. UpsB-Q-1 (blue), UpsB-Q-2 (red), UpsB-Q-3 (pink) and UpsB-Q-4 (green). For the four sequences, T m 's are about 50°C and the proportion of folded G-quadruplexes at 37°C is above 85%.Back to article page
