In addition of screening the entire iGEM registry, we have developped a tool to help a biology iGEM team. This team is ________________________________. It consisted in finding the DNA sequence of the primer, given three input sequences: the two sequences that will undergo the PCR, and the complete resulting sequence.

The software will find 4 primers: the forward primer overlapping with the first input, the reverse user primer that overlaps with the first sequence and the gap sequence added on the PCR, the forward user sequence, overlapping with the second sequence and the gap sequence, and endly the reverse primer, which overlaps with the second sequence. If some suffix, prefix or terminator are added on the full sequence, they will be added in the forward and reverse primers. To detect the length of the primers, we search for the correct length that will have the desired melting temperature. This melting temperature is calculated with the equation:

                    deltaH
     Tm= -------------------------------  - 273.15 + 16.6log[Na+]
            -10.8 + deltaS + Rln([oligo]/4)

with R = 1.987 cal/(mol K) Gas constant, [oligo] = 5E-07 M, [Na+] = 0.05 M

This tool will be useful also for biologist working on the VBI lab, as they had to do it manually before, and it was pretty slow and subject to human errors.

An executable with the script to use it (on windows or on linux) are available here:_________. The source code of this software is also available ____________.
