DescriptionLentiBrite™ GFP-LC3-II Enrichment Kit (Flow Cytometry)
OverviewAutophagy, a degradative pathway that provides recycled nutrients to cells under stress, plays both protective and deleterious roles in many diseases, including cancer, neurodegeneration, and infections. Members of the LC3 family play a key role in the maturation of the autophagosome, the central organelle of autophagy. LC3 precursors, diffusely distributed in the cytosol, are proteolytically processed to form LC3-I. Upon initiation of autophagy, the C-terminal glycine is modified by addition of a phosphatidylethanolamine (PE) to form LC3-II, which translocates rapidly to nascent autophagosomes in a punctate distribution. DNA constructs encoding fluorescent proteins fused to LC3 are widely employed for introduction into cells for monitoring autophagosome formation by fluorescence microscopy.
EMD Millipore’s LentiBrite™ GFP-LC3 lentiviral particles provide bright fluorescence and precise localization to enable live cell analysis of autophagy in difficult-to-transfect cell types. The

LentiBrite™ GFP-LC3-II Enrichment Kit (Flow Cytometry) combines our GFP-LC3 lentiviral particles with a selective permeabilization procedure for GFP-LC3 transduced cells that allows release of cytosolic LC3-I and retention of autophagosome-bound LC3-II. This procedure allows detection of autophagosome density by flow cytometry.

Application NotesEMD Millipore’s LentiBrite™ GFP-LC3 lentiviral particles provide bright fluorescence and precise localization to enable live cell analysis of autophagy in difficult-to-transfect cell types. The LentiBrite™ GFP-LC3-II Enrichment Kit (Flow Cytometry) combines our GFP-LC3 lentiviral particles with a selective permeabilization procedure for GFP-LC3 transduced cells that allows release of cytosolic LC3-I and retention of autophagosome-bound LC3-II. This procedure allows detection of autophagosome density by flow cytometry.

For optimal fluorescent analysis, it is recommended to analyze the target expression level within 24-48 hrs after transfection/infection for optimal live cell analysis, as fluorescent intensity may dim over time, especially in difficult-to-transfect cell lines. Infected cells may be frozen down after successful transfection/infection and thawed in culture to retain positive fluorescent expression beyond 24-48 hrs. Length and intensity of fluorescent expression varies between cell lines. Higher MOIs may be required for difficult-to-transfect cell lines.
