The Incucyte® Neurolight Red Lentivirus Reagent is a third generation lentiviral-based vector encoded with an redfluorescent protein (mKate2) driven off of a synapsin promoter designed to efficiently transduce multiple cell types. Our extensive validation experiments have shown that expression of this red fluorescent protein does not negatively alter functional cell biology (e.g. morphology, neurite outgrowth, and neurite branching) of neurons in co-culture with astrocytes. In combination, the Incucyte® Live-Cell Analysis System (configured with a green/red optical module), Incucyte® Neurotrack Software (Cat. No. 9600-0010), and the Neurolight Red Lentivirus provide an integrated solution for kinetically measuring neurite dynamics in vitro.
Key Features
Enables quantitation of neurite-specific metrics, such as neurite length, branch points and cell body clusters in co-cultures of neurons or neuronal cell lines with astrocytes.
- Efficiently infects multiple neuronal cell types, including cell lines, primary and stem cell-derived cultures
- Synapsin-promoter driven expression of mKate2, a red fluorescent protein, ensures minimal expression in non-neuronal cell types
- Reagent is non-perturbing to neuronal cell biology
- Each vial contains 0.45 mL of reagent, sufficient for at least 1 x 96-well plate
