A15143K_PURE_LC3_Antibody_1_021218
IHC staining of anti-LC3 antibody (clone A15143K) on formalin-fixed paraffin-embedded human and rat brain tissues. Following antigen retrieval using Sodium Citrate H.I.E.R., the tissues were incubated with the primary antibody at 5 µg/ml overnight at 4°C. BioLegend’s Ultra-Streptavidin (USA) HRP Detection Kit was used for detection followed by hematoxylin counterstaining, according to the protocol provided.

    SH-SY5Y neuroblastoma cells were fixed with 4% paraformaldehyde, and then permeabilized with 0.1% Triton x-100 for 20 minutes. Cells were blocked with 2% normal goat serum for 30 minutes at room temperature, and then incubated with anti-LC3 antibody (clone A15143K) at 1 µg/mL for three hours at room temperature. Alexa Fluor® 488 conjugated anti-mouse IgG (green) was used as secondary antibody at 1 µg/mL. Cells were then incubated with anti-Tubulin β3 (TUBB3) antibody (clone TUJ1) Alexa Fluor® 647 (pink) at 1 µg/mL overnight at 4°C. Nuclei were stained with Hoechst 33342 (blue) at 5 µg/mL for 10 minutes at room temperature. Images were captured with a 60X objective.

Description

Microtubule-associated protein light chain 3, commonly known as LC3, is a central protein in the autophagy pathway and functions in autophagosome biogenesis. LC3 is a member of the ATG8 protein family and expressed as three isoforms: LC3A (MAP1LC3A), LC3B (MAP1LC3B), and LC3C (MAP1LC3C). Newly synthesized LC3 is hydrolyzed by the cysteine protease ATG4B to produce the active cytosolic form termed LC3I. Through a series of reactions involving other ATGs, LC3I becomes attached to phosphatidylethanolamine. This lipid modified form is termed LC3II, and is involved in autophagosomes membrane expansion and fusion events. LC3 is widely used as a marker for autophasomes. Defects in autophagy machinery have been associated with multiples diseases including neurodegenerative disorders.
