DNA polymerase having ability to reduce innate selective discrimination against fluorescent dye-labeled dideoxynucleotides

摘要

The invention relates to genetic modification of DNA polymerase to reduce innate selective sequence-related discrimination against incorporation of fluorescent dye-labeled ddCTP and ddATP in the enzymatic reaction for preparation of samples for automated fluorescent dye-labeled terminator DNA sequencing. The modified DNA polymerases are more resistant to heat inactivation and are more effective in dideoxynucleotide incorporation than current DNA polymerases.
