    Product Information

    Product Description

    This Cell Signaling Technology® antibody is the biotinylated version of the unconjugated LC3B (D11) Rabbit Monoclonal Antibody #3868 and is expected to exhibit the same species cross-reactivity. The concentration of the biotinylated antibody is 500 ug/ml. Peptide ELISA data were generated using the biotinylated antibody. Western blot data were generated using the unconjugated antibody.
    MW (kDa) 14, 16

    Product Usage Information

    Biotinylated antibodies are ideal for immunoassay technologies and high-throughput ELISA platforms that require antibody pairs where both antibodies are from the same host. Platforms utilizing biotinylated antibodies include, but are not limited to, MSD, xMAP, Quanterix Simoa, AlphaLISA, AlphaScreen, HTRF, LANCE, and TR-FRET.

    Optimal dilutions/working concentrations should be determined by the end user. Please contact us if you require the antibody clone biotinylated at a different concentration, a carrier-free formulation, or a more customized packaging solution.
    Application Dilution
    Western Blotting 1:1000

    Storage

    Supplied in 140 mM NaCl, 3 mM KCl, 10 mM sodium phosphate (pH 7.4) dibasic, 2 mM potassium phosphate monobasic, 2 mg/mL BSA, and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    LC3B (D11) Rabbit Monoclonal Antibody (Biotinylated) detects endogenous levels of total LC3B protein. Cross-reactivity may occur with other LC3 isoforms. Stronger reactivity is observed with the type II form of LC3B. Weaker reactivity is observed with rodent LC3B.

    Background

    Autophagy is a catabolic process for the autophagosomic-lysosomal degradation of bulk cytoplasmic contents (1,2). Autophagy is generally activated by conditions of nutrient deprivation, but it has also been associated with a number of physiological processes including development, differentiation, neurodegenerative diseases, infection, and cancer (3). Autophagy marker Light Chain 3 (LC3) was originally identified as a subunit of microtubule-associated proteins 1A and 1B (termed MAP1LC3) (4) and subsequently found to contain similarity to the yeast protein Apg8/Aut7/Cvt5 critical for autophagy (5). Three human LC3 isoforms (LC3A, LC3B, and LC3C) undergo posttranslational modifications during autophagy (6-9). Cleavage of LC3 at the carboxy terminus immediately following synthesis yields the cytosolic LC3-I form. During autophagy, LC3-I is converted to LC3-II through lipidation by a ubiquitin-like system involving Atg7 and Atg3 that allows for LC3 to become associated with autophagic vesicles (6-10). The presence of LC3 in autophagosomes and the conversion of LC3 to the lower migrating form, LC3-II, have been used as indicators of autophagy (11).
