Consensus-degenerate hybrid oligonucleotide primers for amplification of distantly related sequences.

We describe a new primer design strategy for PCR amplification of unknown targets that are related to multiply-aligned protein sequences. Each primer consists of a short 3' degenerate core region and a longer 5' consensus clamp region. Only 3-4 highly conserved amino acid residues are necessary for design of the core, which is stabilized by the clamp during annealing to template molecules. Duri...

iCODEHOP: a new interactive program for designing COnsensus-DEgenerate Hybrid Oligonucleotide Primers from multiply aligned protein sequences

PCR amplification using COnsensus DEgenerate Hybrid Oligonucleotide Primers (CODEHOPs) has proven to be highly effective for identifying unknown pathogens and characterizing novel genes. We describe iCODEHOP; a new interactive web application that simplifies the process of designing and selecting CODEHOPs from multiply-aligned protein sequences. iCODEHOP intelligently guides the user through th...

CODEHOP (COnsensus-DEgenerate Hybrid Oligonucleotide Primer) PCR primer design

We have developed a new primer design strategy for PCR amplification of distantly related gene sequences based on consensus-degenerate hybrid oligonucleotide primers (CODEHOPs). An interactive program has been written to design CODEHOP PCR primers from conserved blocks of amino acids within multiply-aligned protein sequences. Each CODEHOP consists of a pool of related primers containing all pos...

Identifying distantly related protein sequences

The most powerful method available today for inferring the biological function of a gene (or the protein that it encodes) from its sequence is similarity searching on protein and DNA sequence databases. With the development of rapid methods for sequence comparison, both with heuristic algorithms and powerful parallel computers, discoveries based solely on sequence homology have become routine. ...

PriFi: using a multiple alignment of related sequences to find primers for amplification of homologs

Using a comparative approach, the web program PriFi (http://cgi-www.daimi.au.dk/cgi-chili/PriFi/main) designs pairs of primers useful for PCR amplification of genomic DNA in species where prior sequence information is not available. The program works with an alignment of DNA sequences from phylogenetically related species and outputs a list of possibly degenerate primer pairs fulfilling a numbe...
