Greene SCPrimer: a rapid comprehensive tool for designing degenerate primers from multiple sequence alignments
Polymerase chain reaction (PCR) is widely applied in clinical and environmental microbiology. Primer design is key to the development of successful assays and is often performed manually by using multiple nucleic acid alignments. Few public software tools exist that allow comprehensive design of degenerate primers for large groups of related targets based on complex multiple sequence alignments...
متن کاملGemi: PCR Primers Prediction from Multiple Alignments
Designing primers and probes for polymerase chain reaction (PCR) is a preliminary and critical step that requires the identification of highly conserved regions in a given set of sequences. This task can be challenging if the targeted sequences display a high level of diversity, as frequently encountered in microbiologic studies. We developed Gemi, an automated, fast, and easy-to-use bioinforma...
متن کاملMAD-DPD: designing highly degenerate primers with maximum amplification specificity.
This work introduces minimum accumulative degeneracy, a variant of the degenerate primer design problem, which is particularly useful when a large number of sequences are to be covered by a set of restricted number of primers. A primer set, which is designed on a minimum accumulative degeneracy basis, especially helps to reduce nonspecific PCR amplification of undesired DNA fragments, as fewer ...
متن کاملStochastic pairwise alignments
MOTIVATION The level of sequence conservation between related nucleic acids or proteins often varies considerably along the sequence. Both regions with high variability (mutational hot-spots) and regions of almost perfect sequence identity may occur in the same pair of molecules. The reliability of an alignment therefore strongly depends on the level of local sequence similarity. Especially in ...
متن کاملGlobal Pairwise Sequence Alignments with Multiple Scoring Matrices
A necessity of repeating alignments on a same pair of sequences to select an appropriate scoring function to detect a significance of score motivates us to work on higher performance matching technique. While overlapping each alignments obtained through a set of typical scoring matrix with its default gap cost, we observe significant parameters that may induce a maximum deviation from a referen...
