Description
The BLOCK-iT Alexa Fluor Red Fluorescent Control is an ideal indicator of lipid-mediated transfection efficiency for RNAi experiments, particularly those using the Lipofectamine RNAiMAX Transfection Reagent. The sequence of the BLOCK-iT Alexa Fluor Red Fluorescent Control is not homologous to any known gene, preventing induction of nonspecific cellular events caused by introduction of the duplex into cells. The BLOCK-iT Alexa Fluor Red Fluorescent Control provides: A strong, easily detectable, and photostable Alexa Fluor 555* signal indicating transfection efficiency Chemical modifications for a clearer, more persistent cellular signal than with labeled siRNA Proven correlation of transfection efficiency with Stealth RNAi siRNA and traditional siRNA molecules *This dye can be detected using standard filter sets designed for Alexa Fluor 555, Cy 3, DsRed, Texas Red, or rhodamine fluorophores
