Scientific BackgroundMAP1A and MAP1B are microtubule-associated protein which mediate the physical interactions between microtubules and components of the cytoskeleton (probably involved in autophagosome formation). MAP1A and MAP1B each consist of a heavy chain subunit and 3 different light chain subunits (LC1, LC2 and LC3). MAP1LC3A is one of the light chain subunits and can associate with either MAP1A or MAP1B. The precursor form of MAP1LC3A is cleaved by APG4/ATG4B to form the cytosolic form LC3-1. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form the membrane-bound form, LC3-II. MAP1LC3A is most abundant in heart, brain, liver, skeletal muscle and testis but is absent in thymus and peripheral leukocytes.
Left: Flow cytometry analysis of human SHSY-5Y cells of MAP1LC3A with M-1725-100. Fixing and Permeabilization of cells: Absolute methanol and 0.1% Tween-20 in PBS, Primary antibody: Mouse Monoclonal antibody to MAP1LC3A (cat # M-1725-100, 2 μg per ~10^6 cells) for 15 minutes at room temperature, Secondary antibody: Goat anti-mouse PE labelled secondary antibody (1:1000 fold dilution) with incubation for 15 minutes in dark at room temperature. Non-specific Control IgG, clone X63 (cat # M-1249-200) was used under same conditions as negative control (black dashed). Flow cytometry data and results were generated using Orflo Moxiflow instrument and protocols. The data demonstrates specific staining of MAP1LC3A expressed in human neuronal cell line SHSY-5Y using cat # M-1725-100. Right: Detection of MAP1LC3A in human SHSY-5Y cell lysates (20 µg/lane) by Western Blotting. SDS-PAGE: 4-20% Bis-Tris denatured, reduced; Transfer: Tris-Glycine buffer; Membrane: nitrocellulose (0.2 µm); Blocking: 5% skim milk in TBST, 1 hour at RT; Primary antibody: overnight at 4°C (10 µg/mL); Secondary antibody: anti-mouse-HRP (1/10000) 2 hours at RT; Detection: Enhanced Chemiluminescence Substrate with LiCor C-DiGit Blot Scanner. The broad band seen on WB indicates binding of Cat # M-1725-100 to a broad protein band with a Molecular Weight of ~14 kDa. Predicted molecular weight of MAP1LC3A is ~14.5 kDa.
Immunofluorescence analysis of MAP1LC3A expression in rat C6 glioma cells. Fixed (4% formaldehyde), permeabilized, and blocked (10% normal horse serum, 0.1% Triton X100) C6 cells were incubated with MAP1LC3A antibody M-1725-100 (2 µg/mL, green) for 1 hour. Primary antibody binding was visualized with a secondary donkey anti-mouse-CF488A antibody (4 µg/mL, 1 hour incubation). Cell nuclei were stained with Hoechst dye (blue). MAP1LC3A-IR is observed throughout the cytoplasm. Magnification: 100x.
