Figure 2. Table 1 Small interfering RNA design software programs. Conclusion The efficacy of each siRNA is known to be widely varies depending on its sequence in mammalian cells, and only a limited fraction of randomly designed siRNAs is functional.

Design appropriate controls. A complete siRNA experiment should include a number of controls to ensure the validity of the data. The editors of Nature Cell Biology have recommended several controls 2.

Two of these controls are: A negative control siRNA with the same nucleotide composition as your siRNA but which lacks significant sequence homology to the genome.

To design a negative control siRNA, scramble the nucleotide sequence of the gene-specific siRNA and conduct a search to make sure it lacks homology to any other gene. Perhaps the best way to ensure confidence in RNAi data is to perform experiments, using a single siRNA at a time, with two or more different siRNAs targeting the same gene.

Prior to these experiments, each siRNA should be tested to ensure that it reduces target gene expression by comparable levels. Most of the designs had two inverted repeats separated by a short spacer sequence and ended with a string of T's that served as a transcription termination site.

The selection of siRNA target sequence, the length of the inverted repeats that encode the stem of a putative hairpin, the order of the inverted repeats, the length and composition of the spacer sequence that encodes the loop of the hairpin, and the presence or absence of 5'-overhangs, vary among different reports Ambion will synthesize a complementary pair of siRNA oligonucleotides according to your sequence.
