摘要:
The invention relates to kits and methods for panhandle PCR amplification of a region of DNA having an unknown nucleotide sequence, wherein the region flanks a region of a leukemia-associated gene having a known nucleotide sequence in a human patient. Amplification of an unknown region flanking a known region of a leukemia-associated gene permits identification of a translocation partner of the gene or identification of a duplicated sequence within the gene. The invention further relates to kits useful for performing the methods of the invention, to an isolated polynucleotide, and to primers derived from such an isolated polynucleotide.
摘要:
An iterative and regenerative method for sequencing DNA is described. This method sequences DNA in discrete intervals starting at one end of a double stranded DNA segment. This method overcomes problems inherent in other sequencing methods, including the need for gel resolution of DNA fragments and the generation of artifacts caused by single-stranded DNA secondary structures. A particular advantage of this invention is that it can create offset collections of DNA segments and sequence the segments in parallel to provide continuous sequence information over long intervals. This method is also suitable for automation and multiplex automation to sequence large sets of segments.

摘要:
A method that permits the rapid amplification of unknown DNA that flanks a known site, such that one can walk into an uncharacterized region of DNA. In this method, human genomic DNA is restriction enzyme digested and then ligated to a 5' phosphorylated-oligonucleotide so that the 5' end of each strand of genomic DNA is extended and phosphorylated. The phosphorylated-oligonucleotide is constructed to render 5' end extensions that are complementary to the known sequence. Following denaturation and re-annealing under dilute conditions that promote intrastrand annealing and under high stringency, only those DNA strands containing the known sequence will form a stem-loop structure with a recessed and phosphorylated 5' end, rendering a substrate for a subsequent heat-stable ligation reaction to another oligonucleotide. This second oligonucleotide is complementary to the sequence immediately adjacent to the phosphorylated-oligonucleotide high stringency annealing site. The heat-stable ligation reaction appends a known sequence to the DNA segments containing the two known contiguous DNA sequences used for oligonucleotide annealing. This heat-stable ligation of known sequence permits the subsequent highly specific amplification of the unknown flanking DNA.

The subject invention relates to a method referred to as recombination PCR (RPCR). In the method, the polymerase chain reaction is utilized to add double-stranded homologous ends to DNA. These homologous ends undergo recombination in vivo following transfection of host cells. The placement of these homologous ends, by the amplifying primers permits the rapid cloning of the desired mutant or recombinant, with a minimal number of steps and primers.

摘要:
A method that permits the highly specific PCR amplification of unknown DNA that flanks a known sequence region. In this method, known DNA is placed on the uncharacterized side of that specific sequence that contains the unknown DNA by a DNA polymerase mediated generation of a PCR template that is shaped like a pan with a handle. Generation of this template permits specific amplification of the segment of interest.
