Autophagy

The 2016 Nobel Prize in Physiology or Medicine was awarded to Dr. Yoshinori Ohsumi “for his discoveries of mechanisms for autophagy” [1]. Genetic resources for autophagy study are available. Looking forward to receiving your request.

RDB14601 pMRX-IP-GFP-LC3-RFP Fluorescent probe to evaluate autophagic flux by the rat LC3 fused with GFP and RFP.
RDB14600 pMRX-IP-GFP-LC3-RFP-LC3 delta G Fluorescent probe to evaluate autophagic flux by the rat LC3 fused with GFP and RFP.
  • In order to visualize autophagosome and observe autophagy, MAP1LC3 (LC3) fused with fluorescent proteins as a probe are used. However, the fluorescence of the probe attenuates during autophagy progresses and it is not suitable for quantitative assay of autophagy.
  • Dr. Noboru Mizushima and his colleagues at the University of Tokyo developed a new probe that can expresses GFP-LC3 and RFP-LC3 delta G (lacking glycine (G) at the LC 3 end) simultaneously at equimolar amounts. As autophagy progresses, the fluorescence of GFP-LC3 decays whereas that of RFP-LC3 delta G remains in the cytoplasm as an internal standard. Therefor, the activity of autophagy can be quantified evaluated by the fluorescence intensity ratio of GFP/RFP.
  • Using this probe, autophagic flux was measured in mouse and zebrafish embryos and tissues as well as cultured cells. This is also suitable for analysis of large number of samples.

RDB15088 pcDNA5-GAPDH-HaloTag Expression vector for the visualization of chaperone-mediated autophagy (CMA).
  • The GAPDH-HT indicator is a chaperone-mediated autophagy (CMA) marker consisting of HaloTag and GAPDH which is a typical substrate of CMA. The CMA activity in the cells can be evaluated by using GAPDH-HT indicator and an appropriate under the fluorescent-labeled HaloTag ligand.
