BLOCK-iT™ Fluorescent Oligo provides:

• A strong, easily detectable FITC signal indicating transfection efficiency
• Chemical modifications for a clearer, more persistent cellular signal than labeled siRNA
• Proven correlation of transfection efficiency with Stealth RNAi™ siRNA and traditional siRNA molecules

This makes the BLOCK-iT™ Fluorescent Oligo an ideal indicator of transfection efficiency for RNAi experiments. BLOCK-iT™ Fluorescent Oligo is available in two configurations: one designed for lipid-mediated transfection (2 x 125 μL) at 20 μM and one designed for electro-poration (75 μl) at 1 mM.
