siPOOL Cancer Toolbox

Manipulate Multiple Cancer Pathways Easily and Reliably

The siPOOL Cancer Toolbox is a collection of 10 or more siPOOLs (complex, defined siRNA pools) against highly relevant human cancer genes.  Choose from our pre-defined list of 100 top cancer genes and knock-down gene expression reliably and quickly with this flexible and affordable research solution.

Key Benefits

Quick and reliable loss-of-function phenotypes: siPOOLs are easily applied across cell lines and produce effects within days. The established targeting specificity of siPOOLs ensures reliable results.

Ideal for combinatorial silencing of multiple genes or isoforms: The low working concentration of siPOOLs encourages its combined use with low risk of toxicity. Study functional interactions, target multiple isoforms, or disrupt several pathways at once.

Guaranteed gene silencing: All siPOOLs are guaranteed to silence target genes by ≥ 70% under optimal transfection conditions at 10 nM. A free siPOOL re-design, validation and delivery will be made if this condition is not met.

Flexible choice: Choose your own siPOOLs against 100 of the most highly cited cancer genes. Extend the cancer toolbox with your own special target genes.

Target the top 100 cancer genes

With 46 established oncogenes/tumour suppressors, the top 100 cancer genes are implicated in diverse processes ranging from DNA repair, immune responses and cell cycle control.

Data with siPOOLs - Multiple gene silencing reveals functional interactions

Welsbie et al Multi gene targeting with siPOOLs

Survival assay of retinal ganglion cells demonstrated synergistic gene interactions elucidated by combinatorial application of siPOOLs. Up to four genes were silenced simultaneously with siPOOLs, generating phenotypes that were validated by an orthogonal CRISPR knock-out approach (Data from Welsbie et al., Neuron 2016).

Data with siPOOLs - Efficient gene silencing at low nanomolar concentrations

In-house data showing real-time quantitative PCR analysis of the top 20 cancer genes after siPOOL application at 1 nM in standard cell lines (A549, MCF7, HEK293).

“Having tested over 75,000 siRNA sequences, it is quite apparent that off-target effects dominate siRNA-mediated phenotypes. In contrast, in our hands, siPOOLs have much greater predictive power in that phenotypes we see with these (and we have tested approximately 15) can be reproduced using cells containing conventional knockouts for the same genes. We now routinely use siPOOLs and are moving away from single siRNAs.”

“siPOOLs are highly target-specific and show an efficient knockdown of the target already in the range of low nanomolar concentrations. Another advantage of siPOOLs is that they are able to distinguish very specifically between highly homologous transcript sequences. We are very happy with those siPOOLs, which helped to avoid waste of time and costs within the drug discovery process by producing reliable data.”
