Figure 3From: Optimized expression of Plasmodium falciparum erythrocyte membrane protein 1 domains in Escherichia coliBinding to heparin. Recombinant GST-DBL1α of FCR3S1.2 was purified from cultures with induction at mid-log (lane 1) and post-log stage (lane 2) and bound to heparin. Protein expressed by bacteria at post-log stage showed considerably higher affinity to heparin.Back to article page
