amplification of gc-rich putative mouse pep promoter using betaine and dmso in ammonium sulfate polymerase chain reaction buffer

Amplification of GC-rich Putative Mouse PeP Promoter using Betaine and DMSO in Ammonium Sulfate Polymerase Chain Reaction Buffer

BACKGROUND Recently, we have shown that peroxisomal protein expression was induced upon retinoic acid treatment in mouse embryonic stem cells during the process of neurogenesis. Thus, characterization of the respective promoter could elucidate the molecular aspects of transcriptional regulation of this gene. METHODS Using the conventional software programs for promoter prediction, a putative ...

DMSO and Betaine Greatly Improve Amplification of GC-Rich Constructs in De Novo Synthesis

In Synthetic Biology, de novo synthesis of GC-rich constructs poses a major challenge because of secondary structure formation and mispriming. While there are many web-based tools for codon optimizing difficult regions, no method currently exists that allows for potentially phenotypically important sequence conservation. Therefore, to overcome these limitations in researching GC-rich genes and ...

SPECIFIC 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...

Betaine 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...

Polymerase Chain Reaction and Qf3 Replicase Amplification

The polymerase chain reaction (PCR) and Q/3 replicase are two methods in which nucleic acid polymerases are used for amplification. Although these approaches share many similar problems concerning target contamination and probe specificity, they differ dramatically in their mechanisms of action and modes of application.The PCR method amplifies target sequences between two priming oligonucleotid...
