Immunogen A synthetic peptide made to an internal portion of the human LC3 protein sequence (between residues 25-121).
Specificity This antibody detects both LC3A and LC3B.
Cross-Reactivity (Details) Predicted to react with Xenopus,bovine based on 100% sequence homology.
Purification affinity purified
Alternative Name LC3B
Background Autophagy is a process of intracellular bulk degradation in which cytoplasmiccomponents, including organelles, are sequestered within double-membrane vesiclesthat deliver the contents to the lysosome/vacuole for degradation. Duringmacroautophagy, the sequestering vesicles, termed autophagosomes, fuse with thelysosome or vacuole resulting in the delivery of an inner vesicle (autophagic body) intothe lumen of the degradative compartment. There are 16 proteins participating in theautophagy pathway in human. The autophagy protein LC3, a mammalian homologue ofAtg8, was originally identified as microtubule-associated protein 1 light chain 3. It is acomponent of both the MAP1A and MAP1B microtubule-binding domains and theheavy-chain independent regulation of LC3 expression might modify MAP1microtubule-binding activity during development. LC3 is the only known mammalianprotein identified that stably associates with the autophagosome membranes. LC3-I iscytosolic and LC3-II is membrane bound and enriched in the autophagic vacuolefraction. The detection of LC3-I to LC3-II conversion is a useful and sensitive marker fordistinguishing autophagy in mammalian cells. Alternate Names: anti-Microtubule-associated proteins 1A/1B light chain 3B MAP1A/MAP1B LC3 Bantibody, anti-MAP1A/b light chain 3 B antibody, anti-Autophagy-related protein LC3 Bantibody, anti-Autophagy-related ubiquitin-like modifier LC3 B antibody.
Gene Symbol: MAP1LC3A
Gene ID 84557, 66734, 64862
UniProt Q9GZQ8
Research Area Cancer, Autophagy, Cytoskeleton
Application Notes This LC3 antibody is useful for Western blot, Immunocytochemistry/Immunofluorescence (PMID 21545732), Immunoprecipitation and Immunohistochemistry paraffin embedded sections. By Western blot bands are seen at ~19 kDa, representing LC3-I, and ~17 kDa, representing LC3-II. In ICC/IF, cytoplasmic staining was observed in HeLa cells.Use in FLOW cytometry reported in scientific literature ( PMID 24419333)
Recommended dilutions: Flow Cytometry, Immunocytochemistry/Immunofluorescence 1:100-1:300, Immunohistochemistry 1:200-1:400, Immunohistochemistry-Frozen, Immunohistochemistry-Paraffin 1:200-1:400, Immunoprecipitation 20 µg / 500 µg of lysate, Western Blot 2 µg/mL
Protocol Western Blot protocol specific for LC3 Antibody Western Blot Protocol
1. Perform SDS-PAGE (4-12 %) on samples to be analyzed, loading 40 µg of total protein per lane.
. Transfer proteins to Nitrocellulose according to the instructions provided by the manufacturer of the transfer apparatus.
. Rinse membrane with dH2O and then stain the blot using ponceau S for 1-2 minutes to access the transfer of proteins onto the nitrocellulose membrane. Rinse the blot in water to remove excess stain and mark the lane locations and locations of molecular weight markers using a pencil.
. Rinse the blot in TBS for approximately 5 minutes.
. Block the membrane using 5 % non-fat dry milk + 1 % BSA in TBS for 1 hour at room temperature (RT).
. Rinse the membrane in dH2O and then wash the membrane in wash buffer [TBS + 0.1 % Tween] 3 times for 10 minutes each.
. Dilute the rabbit anti-LC3 primary antibody in blocking buffer and incubate 1 hour at RT.
. Rinse the membrane in dH2O and then wash the membrane in wash buffer [TBS + 0.1 % Tween] 3 times for 10 minutes each.
. Apply the diluted rabbit-IgG HRP-conjugated secondary antibody in blocking buffer (as per manufacturer's instructions) and incubate 1 hour at room temperature.
. Wash the blot in wash buffer [TBS + 0.1 % Tween] 3 times for 10 minutes each (this step can be repeated as required to reduce background).
. Apply the detection reagent of choice in accordance with the manufacturers instructions (we used BioFX Super Plus ECL). Note: Tween-20 can be added to the blocking or antibody dilution buffer at a final concentration of 0.05-0.2 %, provided it does not interfere with antibody-antigen binding.I. Deparaffinization: A. Treat slides with Xylene: 3 changes for 5 minutes each. Drain slides for 10 seconds between changes.B. Treat slides with 100 % Reagent Alcohol: 3 changes for 5 minutes each. Drain slides for 10 seconds between changes.II. Quench Endogenous Peroxidase: To Prepare 200 mL of Quenching Solution: Add 3 mL of 30 % Hydrogen Peroxide to 200 mL of Methanol.**Use within 4 hours of preparationA.Place slides in peroxidase quenching solution: 15-30 minutes.III. Retrieve Epitopes: A. Preheat Citrate
Restrictions For Research Use only
Format Liquid
Concentration 1.0 mg/mL
Buffer Tris-glycine, 150 mM NaCl, Sodium Azide
Preservative Sodium azide
Precaution of Use WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice Avoid freeze-thaw cycles
Storage -20 °C
Storage Comment Aliquot and store at -20 °C or -80 °C.
