Scientific Background:Autophagy is an alternative process of proteasomal degradation for some long-lived proteins or organelles. Alterations in the autophagic-lysosomal compartment have been linked to neuronal death in many neurodegenerative disorders as well as in transmissible neuronal pathologies (prion diseases). Genetic studies in yeast have shown that Autophagy-defective Gene-8 (Atg-8) represents a specific marker for autophagy. Among the four families of mammalian Atg8-related proteins only LC3 (Microtubule-associated Protein1 Light Chain 3) is expressed at sufficient high levels and efficiently recruited to autophagic vesicles in cells and tissues. During autophagy the cytoplasmic form, LC3-I is processed and recruited to autophagosomes, where LC3-II is generated by site specific proteolysis near to the C-terminus. Autophagic vacuoles have been also reported frequently in cardiomyopathies or muscle cells exposed to different experimental settings.
Regulatory Status:RUO - Research Use Only
LC3B monoclonal antibody (2G6) Western blot
Figure: Western blot analysis of endogenous LC3 using MAb to LC3B (Prod. No. ALX-803-081).Method: Whole cell lysates of untreated  tumor cells were applied to SDS-PAGE and transferred to a PVDF membrane. The immunoblot was probed with Monoclonal Antibody to LC3 (2G6) (Prod. No. ALX-803-081)  (0.5 µg/ ml) for 1h at RT and developed by ECL (exposure time: 30 sec).
