Fluorescence-based directed termination PCR: direct mutation characterization without sequencing.
We describe a fluorescence-based directed termination PCR (fluorescent DT-PCR) that allows accurate determination of actual sequence changes without dideoxy DNA sequencing. This is achieved using near infrared dye-labeled primers and performing two PCR reactions under low and unbalanced dNTP concentrations. Visualization of resulting termination fragments is accomplished with a dual dye Li-cor ...
متن کاملDirected termination PCR: a one-step approach to mutation detection.
We describe a novel PCR-based method that allows the generation of nested termination fragments by integrating both selective DNA amplification and directed chain termination into a single PCR reaction. These termination fragments can be examined for sequence variation in either denaturing or non-denaturing polyacrylamide gels. This method provides a one-step and highly effective approach for t...
متن کامل[ABO genotyping by PCR-direct sequencing method].
OBJECTIVE To analyze the sequence difference between human A, B, and O alleles and establish the method of ABO genotyping by PCR direct sequencing. METHODS PCR-direct sequencing technique was used to analyze two regions of cDNA from A transferase gene, 233-433 and 660-788. RESULTS Two nucleotide substitutions at 258th and 297th were found in 233-433 region, and a nucleotide substitution at ...
متن کاملDirect PCR sequencing with boronated nucleotides.
A method is described to simultaneously amplify and sequence DNA using a new class of nucleotides containing boron. During the polymerase chain reaction, boron-modified nucleotides, i.e. 2'-deoxynucleoside 5'-alpha-[P-borano]-triphosphates, are incorporated into the product DNA. The boranophosphate linkages are resistant to nucleases and thus the positions of the boranophosphates can be reveale...
