Biological Activity for Polybrene

Polybrene is a cationic polymer that improves lentiviral and adenoviral transduction efficiency in mammalian cells in vitro. It also enhances DNA transfection in many types of cells. It has a neutralizing effect on negatively charged DNA and viral particles which facilitates their attachment and entry into host cells. Polybrene is suitable for use with CRISPR/Cas9 protocols.

Polybrene is a lyophilized solid and can be prepared as a stock solution by adding 1 mL of sterile ultra-pure water directly to the vial (final stock concentration 10 mg/mL).

For further information view the product protocol.
