Primer Explorer V5 Link

The software is engineered to handle the unique spatial and thermodynamic requirements of the LAMP assay: Six-Primer Architecture : Automatically designs the four essential primers ( ) and two optional loop primers ) that accelerate the reaction time by up to one-third. Spatial Constraints : Ensures the distance between the ends (the amplified region) stays between 120 and 160 bases , and the loop-forming region (from the ) remains between 40 and 60 bases Dual Operating Modes

PrimerExplorer V5 incorporates several advanced functionalities to improve assay specificity and sensitivity: Mutation-Site Awareness

A graphical interface shows exactly where each primer sits on the gene structure (exons as boxes, introns as lines), allowing researchers to manually verify design logic. primer explorer v5

In both cases, the gDNA template is either too long to amplify efficiently (large intron) or cannot bind at all (junction-spanning). This ensures that only cDNA (made from mRNA) is detected.

Click "Generate" to let the software identify potential primer sets. V5 usually ranks these based on a "demerit point" system—lower scores indicate a "better" primer set. The software is engineered to handle the unique

Primer Explorer v5 is a cloud-based, algorithmic software platform developed primarily by PrimerDigital Ltd. (and integrated into various commercial thermocycler ecosystems). Unlike basic primer design tools that simply check for melting temperature (Tm) and GC content, version 5 introduces and secondary structure prediction at thermodynamic equilibrium .

While powerful, Primer Explorer V5 is not a universal solution: This ensures that only cDNA (made from mRNA) is detected

Primer specificity is the degree to which the primer binds only to the intended target sequence. V5 utilizes updated thermodynamic parameters to predict binding stability. It rigorously checks for primer-dimer formation (where primers bind to each other rather than the DNA) and secondary structures (like hairpin loops) that could inhibit the reaction.

: Unlike version 4, V5 allows users to use MSA results as input to design "Common" or "Specific" primers for targeting gene families or avoiding cross-reactivity.

Old tools: Flag obvious dimers but miss cross-dimers in multiplex. v5 solution: The cross-dimer matrix highlights interactions you never considered, such as between your forward primer for Gene A and your reverse primer for Gene B.
