SMARTBASE SIRNA	SmartBaseTM siRNA Modifications: Design Guide for Enhanced siRNA Performance				1 each	$25.00

SmartBase^TM siRNA Modifications: Design Guide for Enhanced siRNA Performance.
Gene Link presents various design options for synthesizing effective siRNAs, probes and oligos based on the application. SmartBase^TM siRNA can be synthesized in a predetermined way to exhibit the features that is desired; for instance to increase duplex stability 2'-fluoro C and U bases and 5-methyl dC and 2-Amino dA can be substituted, for nuclease resistance the phosphodiester linkages can be selectively substituted with phosphorothioate and for cellular delivery we may add cholesterol to the synthetic oligonucleotide sequence or modify with thiol or amine for post synthesis conjugation with Cell Penetrating Peptides (CPP's) that are known to aid transport and facilitate cellular uptake.
The premise of this product guide is to introduce the use of SmartBase^TMmodifications and go beyond the traditional use of standard DNA and RNA bases for constructing synthetic siRNAs in particular and as well emphasize their use in primers, oligos and probes. SmartBase^TMmodifications also introduces the molecular biologists to develop a cross-disciplinary synergy of molecular applications to a wealth of nucleic acid chemistry tools available as modified bases to impart specific properties compatible with biological applications and gene expression pathways.
