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. |
- 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.
