PCR primer design, in silico PCR, oligonucleotide assembly and analyses

PCR tool provides comprehensive and professional facilities for designing primers for most PCR applications and their combinations: standard, multiplex, long distance, inverse, real-time, unique, group-specific, bisulphite modification assays, polymerase extension PCR multi-fragments assembly cloning (OE-PCR); and microarray design;
in silico (virtual) PCR or primers and probes search or in silico PCR against whole genome(s) or a list of chromosome - prediction of probable PCR products and search of potential mismatching location of the specified primers or probes;
comprehensive primer test, the melting temperature calculation for standard and degenerate oligonucleotides including LNA and other modifications, primer PCR efficiency, primer's linguistic complexity, and dilution and resuspension calculator;
analyzes different features of multiple primers simultaneously, the melting temperature, GC content, sequence linguistic complexity, primer PCR efficiency and molecular weight, the extiction coefficient, the optical density (OD);
primers (probes) are analyzed for all primer secondary structures including G-quadruplexes detection, hairpins, self-dimers and cross-dimers in primer pairs;
tool calculate Tm for primer dimers with mismatches for pure and mixed bases using averaged nearest neighbour thermodynamic parameters and for modifications (inosine, uridine, or LNA);
tool for identifying simple sequence repeat (SSR) loci by analysing the low complexity regions of input sequences;
tool for searching for similar sequences (or primers);
translates nucleotide (DNA/RNA) sequences to the corresponding peptide sequence in all six frames for standard and degenerate DNA and modifications (inosine, uridine);
polymerase chain assembly (PCA) or oligos assembly - created to automate the design oligonucleotide sets for long sequence assembly by ligase chain reaction (LCR) and PCR;
the program includes various bioinformatics tools for patterns analysis of sequences with GC:(G-C)/(G+C), AT:(A-T)/(A+T), CG-AT:(S-W)/(S+W), purine-pyrimidine (R-Y)/(R+Y) skews, CG% content and the melting temperature and considers linguistic sequence complexity profiles.
