A universal restriction site-free cloning method has been developed to precisely insert a DNA fragment into a vector at any desired location without altering any nucleotide(s) in either the DNA fragment or the vector. The technique employs two pairs of chimeric primers, each containing a ribonucleotide. One pair of primers is used to amplify a target DNA fragment and another is used to prepare ...

1 Biological scientists often need to design primers. These are short pieces of DNA used for copying sections of a DNA sequence using the polymerase chain reaction (PCR). Primers have various properties that influence the likelihood of success and scientists wish to quickly and easily select the best primers for amplification of a target sequence. Current web-based primer design software (Prime...

AIMS This work focuses on the development of a method for the identification of pathogenic yeast. With this aim, we target the nucleotide sequence of the RPS0 gene of pathogenic yeast species with specific PCR primers. PCR analysis was performed with both the genomic DNA, whole cells of clinical isolates of Candida species and clinical samples. METHODS AND RESULTS A single pairs of primers, d...

UNLABELLED PREMISE OF THE STUDY New primers were developed for Bignonieae to enable phylogenetic studies within this clade using herbarium samples. • METHODS AND RESULTS Internal primers were designed based on available sequences of the plastid ndhF gene and the rpl32-trnL intergenic spacer region, and the nuclear gene PepC. The resulting primers were used to amplify DNA extracted from her...

adenoviruses are recognized as common human pathogens that are responsible for a wide variety of infectious syndromes. bone marrow transplant patients are prone to life threatening opportunistic infections like adenoviruses. the nested polymerase chain reaction has provided an alternative, sensitive diagnostic method for detection of adenoviruses. in this study we developed pcr from hexon genes...

Uracil-Specific Exision Reagent (USER) fusion is a recently developed technique that allows for assembly of multiple DNA fragments in a few simple steps. However, designing primers for USER fusion is both tedious and time consuming. Here, we present the Primer Help for USER (PHUSER) software, a novel tool for designing primers specifically for USER fusion and USER cloning applications. We also ...

In this study, we redesigned and evaluated primers for the class Actinobacteria. In silico testing showed that the primers had a perfect match with 82% of genera in the class Actinobacteria, representing a 26-213% improvement over previously reported primers. Only 4% of genera that displayed mismatches did so in the terminal three bases of the 3' end, which is most critical for polymerase chain...

various molecular techniques are available to make differences and to study the genetic divergences among species and populations, of which the most efficient ones are pcr-based markers. one of these methods, molecular fingerprinting, enables the distinction of closely related populations. issr-primers are universal primers that can be used for such studies. the utility of these primers was tes...

The polymerase chain reaction (PCR) is a potentially interesting diagnostic tool for detecting congenital Trypanosoma cruzi infection at birth. We have compared the sensitivity and capacity of a group of T. cruzi PCR primers in detecting the complete spectrum of known T. cruzi lineages, and to improve and simplify the detection of infection in neonatal blood. We found that the two primers, Tcz1...
