      DescriptionFlowCellect™ GFP-LC3 Reporter Autophagy Assay Kit (CHO)
      OverviewMillipore’s FlowCellect™ GFP-LC3 Reporter Autophagy Assay Kits provide a quantitative solution for studying autophagy and measuring potency of autophagy inducers using flow cytometry. This kit has four unique features:
      1.) The use of a proprietary selective permeabilization solution discriminates between cytosolic LC3 from autophagic LC3 by extracting the soluble cytosolic proteins, while protecting LC3 which has been sequestered into the autophagosome;
      2.) The use of a monomeric GFP is used as a reporter to facilitate the translocation of the fusion protein, as other forms of GFP form dimers and aggregate when over-expressed in the cells, thus making it difficult to be extracted from cytoplasm and impossible to measure translocation by flow cytometry;
      3.) Since autophagy is a constitutive cellular degradation process, the use of an autophagy detection reagent (Autophagy Reagent A) will prevent the lysosomal degradation of LC3, allowing its quantification by flow cytometry.
      4.) The monomeric GFP used in our fusion protein to LC3 is attached on the 5' end (N-terminal fusion), protecting the GFP from Atg4 cleavage, thus, allowing its visualization within the autophagosomes.

      Two host cell lines are offered in either CHO (Chinese Hamster Ovary) or U20S (human osteosarcoma) to assist in your autophagy research. The CHO reporter cell line is ideal for flow cytometry applications, while U20S is suitable for both imaging and flow cytometry.

      Background InformationAutophagy is an intracellular catabolic pathway that causes cellular protein and organelle turnover, and it is associated in diverse diseases including Alzheimer's disease, aging, cancers, and Crohn's disease. It is a tightly regulated process that plays a normal part in cell growth, development, and cellular homeostasis. Autophagy functions as a housekeeping mechanism by disposing of aging and/or dysfunctional proteins and organelles by sequestering and priming for lysosomal degradation. Increasing evidence suggests that not just apoptosis, but autophagy can contribute to cell death and greatly influence general cell health. Malfunctions of autophagy can influence longevity and productivity of cells to function at full capacity.

      During autophagy, LC3 protein is translocated from the cytoplasm to the autophagosome where it is targeted to the lysosome for degradation. The process of autophagy can be categorized into four distinct stages:

      1) Induction and LC3 Translocation: The process is initiated by external/internal stimuli (e.g. nutrient
      2) Autophagosome formation: Unwanted cytosolic proteins and aging organelles are sequestered by a double membrane vesicle, i.e.—”autophagosome”. Formation of this vesicle is coordinated by complexes of Atg proteins (Atg5 and Atg12) that are conjugated, enabling the recruitment of LC3;
      3) Lysosomal docking and fusion: LC3 protein regulates traffic between autophagosome to lysosome. (LC3-I is cytoplasmic; LC3-II is lipidated and sequestered into autophagosomal membrane);
      4) Degradation: Fusion with the lysosome and subsequent breakdown of the autophagic vesicle and its contents.
