Elongation of Primer-templates by archaeal family-B DNA polymerases. Gel electrophoretic analysis of primer strand extension observed with: (A) Pfu-Pol wild type; (B) Pfu-Pol M247R/L381R; (C) Pfu-Pol L381R/K501R; (D) Tkod-Pol. The primer-template used was: 5′-GGGGATCCTCTAGAGTCGACCTGC 3′-CCCCTAGGAGATCTCAGCTGGACGACCGTTCGTTCGAACAGAGG. The primer was labeled at its 5′-terminus with either cyanine 5 (used with wild type Pfu-Pol and the double mutants) or fluorescein (used with Tkod-Pol).
