PrimersList


analyzes different features of multiple primers simultaneously, the melting temperature calculation for standard and degenerate oligonucleotides, GC content, primer PCR efficiency; primers are analyzed for all primer secondary structures including G-quadruplexes detection, hairpins, self-dimers and cross-dimers in primer pairs; sequence linguistic complexity, molecular weight, the extiction coefficient, the optical density (OD);
the optimal temperature of annealing (Ta) calculation for all given primers.

Write or paste your primer sequences to the input field (upper window). The analyzer accepts text and table format (can be copied from an Excel file, for example).
The name and sequence string can be separated with either space or tab, as long as the style is the same for all the primers.
The results will appear instantly in the output fields (lower windows), and update automatically if you make changes to the sequences. The results can be copied and pasted to other programs (Word, Excel, etc.).


IUPAC DNA degenerate code is an extended vocabulary of 15 letters which allows the description of ambiguous DNA code. Each letter represents a combination of one or several nucleotides:
B=(C,G,T), D=(A,G,T), H=(A,C,T), K=(G,T), M=(A,C), N=(A,C,G,T), R=(A,G), S=(G,C), V=(A,C,G), W=(A,T), Y=(C,T).
U=Uracil; I=Inosine; and LNA: dA=E, dC=F, dG=J, dT=L.

The tools are written in Java with NetBeans IDE (Oracle) and require the Java 8 Runtime Environment (JRE) on a computer.

Note: If you don't see the Java Web Start application's Java Web Start button, Java application needs the Java 8 Runtime Environment (JRE) or complete Java Development Kit (JDK), can be downloaded from java.com), and you might need to enable the JavaScript interpreter in your browser so that the Deployment Toolkit script can function properly.

UNDERSTANDING A JAVA ERROR MESSAGE:
If the Java 8 security level is set to "Very High" then no unsigned Java programs are allowed to execute.

Solution:
Add http://primerdigital.com/ site to "Exception Site List", and set "Security Level" to High.
