Applications/Dilutions

Dilutions
  • Flow Cytometry
Application Notes
This LC3 antibody is useful for Immunohistochemistry, Immunocytochemistry/Immunofluorescence, Flow Cytometry and Western blot. In WB a band is seen at ~14 kDa. IHC was done on formalin fixed paraffin embedded sections. In ICC/IF, autophagosome formation has been seen in HeLa cells after treatment with 50uM chloroquine.

Background

LC3 (microtubule-associated protein light chain 3), the most studied autophagy biomarker, was originally identified as a subunit of microtubule-associated proteins 1A and 1B (MAP1LC3) and was later found to contain similarity to yeast protein Apg8/Aut7/Cvt5. Distributed ubiquitously in eukaryotes, LC3 is expressed as 3 splice variants/isoforms (LC3A, LC3B and LC3C) which undergo post-translational processing, wherein, the unprocessed form of LC3 is proteolytically cleaved by Atg4 protease to form LC3-I with carboxyterminal exposed glycine. During autophagy, this exposed glycine of LC3-I is conjugated by Atg7 (an E1-like activity), Atg3 (an E2-like conjugating activity) and by Atg12-Atg5-Atg16L multimers (E3-like ligase activity) to phosphatidylethanolamine (PE) moiety for generating LC3-II. The lipophilic character of PE group facilitates LC3-II insertion into autophagosomes membranes, and as a result LC3-II is degraded when autophagosomes fuse with lysosomes to form autolysosomes for lysus of intra-autophagosomal components by lysosomal hydrolases. Conversion of LC3I to LC3II when correlated with autophagosome numbers is considered as the best marker of autophagy because LC3-II is the only well-characterized protein which specifically localize to autophagic structures throughout autophagy (from phagophore to lysosomal degradation). LC3 is a great tool in research as autophagy is implicated in numerous physiological/pathological processes including responses to exercise/aging, cancer, metabolic and neurodegenerative disorders, and cardiovascular/pulmonary diseases.

FAQs for LC3A Antibody (NBP1-19167PE). (Showing 1 - 1 of 1 FAQ).

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