Confocal immunofluorescent analysis of HeLa cells, chloroquine-treated (50 μM, overnight; left), nutrient-starved with EBSS (4 hr, middle), or untreated (right) using LC3A/B (D3U4C) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) #13082 (green) and β-Actin (8H10D10) Mouse mAb #3700 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).Learn more about how we get our images.
Flow cytometric analysis of HeLa cells, untreated (blue) or treated with chloroquine (50 µM, 16 hr) (green), using LC3A/B (D3U4C) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate).Learn more about how we get our images.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.
NOTE: Cells should be grown, treated, fixed and stained directly in multi-well plates, chamber slides or on coverslips.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

LC3A/B (D3U4C) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) recognizes endogenous levels of total LC3A and LC3B proteins.
Human, Mouse, Rat
Monkey, Xenopus, Bovine, Dog, Pig
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu44 of human LC3B protein (conserved in LC3A).
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for immunofluorescent analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated LC3A/B (D3U4C) XP® Rabbit mAb #12741.
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 post-translational 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).
