ELISA Image 1: FastScan™ Total LC3B ELISA Kit
Figure 1: LC3B protein from untreated and chloroquine-treated HeLa cells is detected by FastScan™ Total LC3B ELISA kit. A much lower signal of LC3B protein is seen in the untreated lysate. The relationship between lysate protein concentration from untreated and chloroquine-treated cells and the absorbance at 450 nm using the FastScan™ Total LC3B ELISA Kit #35172 is shown in the upper figure. The corresponding western blot using a LC3B antibody is shown in the lower figure. Unstarved HeLa cells (80-90% confluence) were treated with chloroquine (50 μM, overnight), and then lysed.

Product Information

Product Description

The FastScan™ Total LC3B ELISA Kit is a sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of LC3B. To perform the assay, sample is incubated with a capture antibody conjugated with a proprietary tag and a second detection antibody linked to HRP, forming a sandwich with LC3B in solution. This entire complex is immobilized to the plate via an anti-tag antibody. The wells are then washed to remove unbound material. TMB is then added. The magnitude of observed signal is proportional to the quantity of LC3B.

*Antibodies in kit are custom formulations specific to kit.

IMPORTANT: This FastScan™ ELISA Kit requires 4 washes at Step 6 of the protocol.

Protocol

Specificity / Sensitivity

The FastScan™ Total LC3B ELISA Kit detects endogenous levels of LC3B as shown in Figure 1. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Species Reactivity:

Human, Mouse, Rat, Monkey

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).
