Bacterial glycerol stock
Bacterial culture transformed with a plasmid vector, grown in the presence of glycerol for freezer stock.
A mixture of four siRNAs provided as a single reagent. siGENOME and ON-TARGETplus SMARTpool reagents are guaranteed* to silence by 75% or better.
Set of four
Four unique siRNAs targeting a single gene provided as individual reagents. Three of four siGENOME and ON-TARGETplus siRNAs are guaranteed* to silence by 75% or better.
Pooled high-titer Lentiviral particles
Transduction-ready high-titer Lentiviral particle format.
Gene families and pathways
Predefined libraries arranged by gene family and/or function.
Arrayed plates
Arrayed in 96-well or 384-well microtiter plates.


*siGENOME and ON-TARGETplus siRNA reagents (SMARTpool and at least 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 and negative control siRNAs). Silencing should be monitored at the mRNA level 24-48 hours after transfection using 100nM siRNA.
