Silencer® siRNA Construction Kit Template Design Tool
This tool will generate oligonucleotide template sequences from a given target siRNA site.

Base:Dye Ratio Calculator
For the Silencer® siRNA Labeling Kit. This calculator determines the extent of fluorescent labeling of an RNA oligonucleotide or siRNA.

Base:Dye Ratio Calculator for the Amino Allyl MessageAmp™ aRNA Kit
This calculator determines the extent of fluorescent labeling of an RNA oligonucleotide or siRNA.

Calculator for Suspension of Dry Single-stranded Oligonucleotides
When provided with nmol, µg or OD₂₆₀ units of dried oligonucleotide synthesized, this calculator will determine how much water or buffer to add to make a solution of the desired µM concentration.

DNA Probe Specific Activity Calculator
This interactive calculator makes it easy to determine the specific activity of DNA probes generated by random priming.

pSilencer™ Expression Vectors Insert Design Tool
This tool generates hairpin siRNA-encoding DNA oligonucleotide inserts from an input siRNA target sequence.

RNA and DNA Concentration Converter
This calculator converts nucleic acid concentrations in ng/ml to pM, and vice versa.

RNA Probe Specific Activity Calculator
This interactive calculator will walk you through the calculations to determine the specific activity of a radiolabeled RNA probe produced by in vitro transcription.

siRNA Target Finder
Quickly identifies potential siRNA target sites within an mRNA sequence and then generates the sequences of the corresponding siRNAs.
