Incucyte^® Cytolight Lentivirus enables efficient, nonperturbing cytoplasmic labeling of living mammalian cells. Incucyte^® Cytolight Lentivirus provides homogeneous expression of a cytoplasmic GFP (green fluorescent protein) or mKate2 (red fluorescent protein) in your choice of primary, immortalized, dividing, or non-dividing cells without altering cell function and with minimal toxicity. These reagents are ideal for generating stable cell populations or clones using puromycin selection. The Incucyte^® Cytolight Lentivirus has been validated for use with the Incucyte^® Live-Cell Analysis System.
