ThermoFidelase 2 is a thermostable DNA unlinking enzyme (type IB DNA topoisomerase). During initial heating of the reactions it removes topological linkage between two strands of plasmid DNA. Because of the topological constraint in the DNA produced by unlinking, the unlinked plasmid strands cannot reform a normal double helix at the lower temperature used for primer annealing and extension. This results in an increased availability of targets for primer annealing and consequently a higher yield of cycle sequencing reaction products.
Fimers are primers with proprietary chemical modifications that inhibit unwanted reactions during cycle sequencing (e.g., primer-dimer artifacts or non-specific PCR). Specially designed Fimers have been successfully used for high throughput sequencing of difficult templates and highly sensitive reactions from minimal amount of templates (1 ng plasmid, 10 ng BAC, 100 ng microbial genomic DNA). Fimers can be designed for any sequencing applications. Kit B106 contains Forward and Reverse Fimers optimized for plasmids containing inserts of AT-rich Plasmodium falciparum DNA.
