PrimerIdent: A web based tool for conserved primer design

UNLABELLED Conserved primers across multiple species and simultaneously specific for a certain isozyme can be rare and difficult to find. PrimerIdent was developed aiming to automate this primer design and selection process in a given nucleotide sequence alignment, providing an intuitive, easy to interpret graphical result, which offers a list of all possible primers that meet the user criteria, with a colour-code identity to each sequence in the alignment. The software here presented is a simple and intuitive web based tool that is suitable for distinguishing very similar nucleotide sequences, such as isozymes-coding sequences, to enable the conserved primer design across multiple species, necessary for approaches that rely on knowing if a primer is suitable for a certain set of pre-aligned sequences, to design a specific primer to a certain sequence variation, or a combination thereof. This extremely useful software can, therefore, be used as a tool for the specific amplification of individual members of multigenic families across related species and also to evaluate the differential expression of isogenes for a given species.
