Autophagy assay cell type - Vestibular schwannoma cells

As autophagy is a multi-step process which includes not just the formation of autophagosomes, but most importantly, flux through the entire system, including the degradation upon fusion with lysosomes, which makes it quite challenging for detection. There are several methods for detection in mammalian cells, including immunoblotting analysis of LC3 and p62 and detection of autophagosome formation/maturation by fluorescence microscopy, Currently, there is no single “gold standard” for determining the autophagic activity that is applicable in every experimental context, hence it is recommended to go for the combined use of multiple methods to accurately assess the autophagic activity in any given biological setting.

LC3B (D11) XP® Rabbit mAb

Cell Signaling Technology

Upstream tips
Sub-confluent cells were treated with 0, 2.5 and 5μM of OSU-T315 for 48 and 72 hours for cell lines, and 72 hours for primary cells. Cells were then harvested and homogenized in lysis buffer (1% SDS, 10mM EDTA, 50mM Tris, pH 8.1) supplemented with protease/phosphatase inhibitor cocktail (Thermo Scientific, Waltham MA).
Protocol tips
Electrophoresis was performed with 25μg or 50μg of protein/lane in a 4-20% gradient SDS- polyacrylamide gel (Thermo Scientific, Waltham MA). Proteins were transferred to PVDF membranes (Millipore, Billerica MA), and probed with specific antibodies of interest and horseradish peroxidase-conjugated secondary antibodies.
Downstream tips
The chemiluminescent signals were detected in X-ray films.
