Recombinant DNA sequences generated by PCR amplification.
The polymerase chain reaction (PCR) has greatly enhanced the field of molecular biology by making numerous regions of the genome (coding and noncoding), in both extant and extinct taxa, accessible for detailed analysis. PCR is especially well suited for applications in systematic biology because conserved regions that flank variable portions of the genome can be used as primer sites for the amp...
متن کاملAmplification of polyomavirus DNA sequences stably integrated in rat cells.
To investigate the mechanism by which the polyomavirus large T antigen (T-Ag) promotes amplification of integrated viral sequences, we constructed a rat cell line, Hy2-ts5, carrying two different inserts of polyomavirus DNA. The first insert, designated the middle T (pmt) locus, was devised to analyze homologous recombination between two defective copies of pmt lying 3.3 kb apart on the same ch...
متن کاملBetaine improves the PCR amplification of GC-rich DNA sequences.
Betaine improves the co-amplification of the two alternatively spliced variants of the prostate-specific membrane antigen mRNA as well as the amplification of the coding cDNA region of c-jun. It is suggested that betaine improves the amplification of these genes by reducing the formation of secondary structure caused by GC-rich regions and, therefore, may be generally applicable to ameliorate t...
متن کاملImproved PCR method for amplification of GC-rich DNA sequences.
Most housekeeping genes, tumor-suppressor genes, and approx 40% of tissue-specific genes contain G+C sequences in their promoter region that were very difficult to amplify. In this report, we propose an improved polymerase chain reaction (PCR) method to be used for successful amplification of the tissue factor pathway inhibitor (TFPI)-2 gene promoter region that exhibit >70% G+C content in a se...
متن کاملSPECIFIC AMPLIFICATION OF ASPERGILLUS FUMlGATUS DNA BY POLYMERASE CHAIN REACTION
Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...
