siRNA Transfection Reagents

An siRNA transfection reagent delivers small interfering RNA duplexes into cultured cells to knock down a target gene at the mRNA level, giving researchers a fast, reversible alternative to CRISPR knockout for loss-of-function studies. Because siRNA silencing is transient and dose-tunable, it's ideally suited to validating gene function, dissecting pathways, de-risking drug targets, and running high-throughput screens.

Amsbio's siRNA transfection reagents are optimized to deliver siRNA at high efficiency across a wide panel of cell types, including many 'hard-to-transfect' lines such as primary cells, stem cells, neurons, and immune cells, while keeping off-target effects and viability impact to a minimum. They are compatible with standard RNAi workflows, giving you reproducible knockdown from screening through target validation.
