Synthesis of oligodeoxyribonucleotides containing degenerate bases and their use as primers in the polymerase chain reaction

Designing Of Degenerate Primers-Based Polymerase Chain Reaction (PCR) For Amplification Of WD40 Repeat-Containing Proteins Using Local Allignment Search Method

Degenerate primers-based polymerase chain reaction (PCR) are commonly used for isolation of unidentified gene sequences in related organisms. For designing the degenerate primers, we propose the use of local alignment search method for searching the conserved regions long enough to design an acceptable primer pair. To test this method, a WD40 repeat-containing domain protein from Beauveria bass...

Application of specific primers and polymerase chain reaction for identification of ralstonia solanacearum biovar2

Use of degenerate primers for polymerase chain reaction cloning and sequencing of the Lactococcus lactis subsp. lactis recA gene.

Two particularly well-conserved stretches in the RecA protein sequences were chosen as templates to synthesize degenerate oligonucleotides, which were used in polymerase chain reaction to amplify an internal recA DNA fragment of Lactococcus lactis subsp. lactis ML3. Using this fragment, we recovered and sequenced the entire lactococcal recA gene. The end of an open reading frame present upstrea...

Identification of potyviruses using the polymerase chain reaction with degenerate primers.

Local areas of conserved amino acid sequence in the replicase and coat proteins of potyviruses were used to select nucleotide sequences for use in the construction of sets of degenerate oligonucleotide primers for amplification of DNA fragments on potyvirus-specific templates in a combined assay of reverse transcription and the polymerase chain reaction (RT-PCR). Sequences selected for the cons...

Characterization of superoxide dismutase Gram-positive bacteria by polymerase chain degenerate primers genes from reaction using

An internal fragment representing approximately 85% of sod genes from seven Gram-positive bacteria was amplified by using degenerate primers in a polymerase chain reaction assay. The DNA sequences of sod polymerase chain reaction products from Clostridium perfringens, Enterococcus faecalis, Enterococcus faecium, Lactococcus lactis, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus ...
