Western blot analysis of extracts from 293T cells, mock transfected (-) or transfected (+) with constructs expressing full-length human LC3A protein (hLC3A), full-length human LC3B protein (hLC3B), and full-length human LC3C protein (hLC3C), using LC3A (E5D5M) Rabbit mAb (upper), LC3B (D11) XP® Rabbit mAb #3868 (upper-middle), LC3C (D3O6P) Rabbit mAb #14736 (lower-middle), or β-Actin (D6A8) Rabbit mAb #8457 (lower).
Western blot analysis of extracts from various cell lines, untreated (-) or treated with Chloroquine #14774 (50 μM, 18 hr; +), using LC3A (E5D5M) Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower). The absence of signal for LC3A in AN3-CA cells is consistent with RNAseq expression data.

LC3A (E5D5M) Rabbit mAb recognizes endogenous levels of total LC3A protein. No cross-reactivity was observed with other family members. Bands of unknown origin are detected between 60 and 80 kDa.
Human, Mouse, Rat
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala96 of human LC3A protein.
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).
