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...
متن کاملEscherichia coli exonuclease III enhances long PCR amplification of damaged DNA templates.
Recent development of the long PCR technology has provided an invaluable tool in many areas of molecular biology. However, long PCR amplification fails whenever the DNA template is imperfectly preserved. We report that Escherichia coli exonuclease III, a major repair enzyme in bacteria, strikingly improves the long PCR amplification of damaged DNA templates. Escherichia coli exonuclease III per...
متن کاملHigh primer concentration improves PCR amplification from random pools.
The success of PCR is partly based on its exponential amplification characteristics. Nevertheless, in practice, the achievable yields are limited. Figure 1A and B shows the quantification of a typical reaction with varying but defined amounts of starting template. Every five cycles an aliquot of the reaction was removed and afterwards the amount of accumulated product quantitated. Although, ini...
متن کاملAn evaluation of direct PCR amplification
AIM To generate complete DNA profiles from blood and saliva samples deposited on FTA® and non-FTA® paper substrates following a direct amplification protocol. METHODS Saliva samples from living donors and blood samples from deceased individuals were deposited on ten different FTA® and non-FTA® substrates. These ten paper substrates containing body fluids were kept at room temperature for vary...
متن کاملExCyto PCR Amplification
BACKGROUND ExCyto PCR cells provide a novel and cost effective means to amplify DNA transformed into competent bacterial cells. ExCyto PCR uses host E. coli with a chromosomally integrated gene encoding a thermostable DNA polymerase to accomplish robust, hot-start PCR amplification of cloned sequences without addition of exogenous enzyme. RESULTS Because the thermostable DNA polymerase is sta...
