The BLOCK-iT™ Fluorescent Oligo provides:

–A strong, easily detectable fluorescein 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
For Research Use Only. Not for use in diagnostic procedures.
