Background: LC3

Autophagy (macroautophagy) is a catabolic process which targets intracellular components such as proteins and organelles for degradation. Originally described as a bulk degradation process, current research supports its selective nature (1). Selective autophagy targets specific cellular components for degradation including the endoplasmic reticulum (2) (ER-phagy), mitochondria3 (mitophagy), peroxisomes (3) (pexophagy), ribosomes (4) (ribophagy) and bacteria (5) (xenophagy). Autophagy relies on a newly formed phagophore, a membrane structure which elongates, sequesters cellular content, and fuses to form a double membrane vesicle known as the autophagosome. Fusion of autophagosomes with lysosomes gives rise to the autophagolysosome, where cellular components are degraded by lysosome hydrolases (1).

Autophagic flux is supported by autophagy-related proteins (Atgs) initially identified in yeast (6,7). The core autophagy machinery is comprised of 17 Atg proteins that play specific roles in autophagosome formation. Among these Atg proteins, Atg8 is not only involved in autophagosome formation but also functions in cargo selection. In mammals, several Atg8 homologues have been identified including microtubule-associated protein 1 light chain 3 alpha, beta and gamma - LC3A, LC3B, and LC3C (8) respectively, as well as GABA type A receptor-associated protein (GABARAP), GABARAP-Like1, and GABARAP-Like2 (9). LC3 (predicted molecular weight 14kD) is ubiquitously expressed and undergoes posttranslational processing after synthesis. First, the cysteine protease Atg4 cleaves a carboxy terminal sequence to generate the cytosolic form LC3-I. Next, E1-like (Atg7) and E2-like (Atg3) enzymes conjugate phosphatidylethanolamine to the newly exposed carboxyterminal glycine, generating LC3-II. Finally, the Atg12-Atg5-Atg16L1 complex participates in LC3 lipidation and autophagosome formation (10). LC3B-I to LC3B-II conversion correlates with autophagosome number and is considered the best marker to monitor autophagy.

FAQs for LC3 Antibody Pack

Showing  1 - 2 of 2 FAQs Showing All

  • Q: Can you recommend a positive control (like a recombinant LC3 purified protein) for LC3B antibody NB100-2220? I am using the antibody on a western blot of mouse tissue.

    A: We recommend NBP1-45308 which is a full length protein that can be used for WB with NB100-2220. 

  • Q: May we ask if it is possible to perform IF to stain LC3-I and LC3-II separately with two different fluorescent colors?

    A: Yes, it is possible to perform IF stain for LC3-I and LC3-II separately with two different fluorescent colors! You will have to use two different primary antibodies and in order to avoid any potential background/cross reactivity issues, I would suggest that you employ conjugated primary antibodies for the testing. 1. Our LC3I antibody (NBP1-78964) has been designed to specifically detect the cytosolic form of the LC3 protein which is actually LC3 I (Note: LC3-II binds to the autophagic membranes). 2. There is not even a single antibody to our knowledge that would exclusively detect the LC3 II form, and you would have to detect LC3II/ autophagic membranes form with an antibody which detects LC3 I/LC3II together. Therefore you may opt second antibody from one of the followings: LC3 Antibody (NB100-2220), LC3 Antibody (NB100-2331), LC3 Antibody (NBP1-19167). All of these mentioned catalog #s come with different options for their conjugated forms and you may select appropriate conjugated forms for performing the IF staining using our explained criteria.
