Mouse On-TARGETplus RTF - Epigenetics

Ideal for labs who want to carry out siRNA screens but lack high-throughput capabilities.


Ready-to-use arrayed siRNA library in single-use plate sets. Just rehydrate and add cells for RNAi screening of human Epigenetic genes. Optimization plates available.

The ON-TARGETplus Mouse Epigenetics siRNA Library targets enzyme classes characterized to play a role in epigenetic mechanisms (see Reference 1). These inheritable factors that regulate genetic expression are of growing importance to scientific understanding of disease progression and trait inheritance. Modification of histones, such as methylation or acetylation, plays a key role in epigenetics as the extent to which DNA is wrapped around these protein complexes will alter the availability of genes in those DNA segments to be activated. The Epigenetics library targets genes which encode histone and DNA modification factors like methyltransferases, acetyltransferases, kinases and deacetylases, in addition to genes with a role in chromatin remodeling and histone ubiquitination.

RTF siRNA libraries are provided as multiple single-use plate sets – just rehydrate and add cells. This unique pre-plated format reduces hands-on time for faster screening results.

ON-TARGETplus modifications combine sense strand inactivation with a novel seed-region modification. This patented siRNA approach is the best strategy to prevent off-target effects caused by both the sense and antisense strands while maintaining high silencing potency.

Highlights

Experimental considerations

DharmaFECT Cell Culture Reagent (DCCR)is recommended for use with RTF libraries to dilute transfection reagents prior to use. DCCR may be purchased separately or accompanying your RTF Optimization Plates

DharmaFECT transfection reagentsare highly recommended for use with RTF libraries and should be purchased separately. Refer to theDharmaFECT Cell Type Guideto find the appropriate formulation for your cell type.

Our siRNA knockdown guarantee

siGENOME and ON-TARGETplus siRNA reagents (SMARTpool and three of four individual siRNAs) are guaranteed to silence target gene expression by at least 75% at the mRNA level when used under optimal delivery conditions (confirmed using validated positive control and measured at the mRNA level 24 to 48 hours after transfection using 100 nM siRNA).

Note: Most siGENOME and ON-TARGETplus siRNA products are highly functional at 5 to 25 nM working concentration.
