LC3A/B antibody | knockout validation | Cell Signaling 12741

This is a knockout-validated antibody summary, based on the publication "p53-dependent autophagic degradation of TET2 modulates cancer therapeutic resistance", as cited below [1]. Labome curates formal publications to compile a list of antibodies with unambiguous specificity within Validated Antibody Database (VAD).

Antibody information

Rabbit monoclonal IgG

Company: Cell Signaling

Antibody: LC3A/B

Catalog number: 12741

Summary: Rabbit monoclonal IgG against a synthetic peptide corresponding to residues surrounding Leu44 of human LC3B protein (conserved in LC3A). Reacts with human, mouse, and rat. It is predicted to react based on 100% sequence homology with Xenopus, bovine, dog, and pig. Suitable for

by western blot, immunohistochemistry (paraffin), immunofluorescence/immunocytochemistry and flow cytometry.

Validation Method

Western blot

Sample

WT and LC3KO p53-inducible HEK293T cells. Cells were lysed on ice by using RIPA lysis buffer (50mM Tris-HCl pH 7.4, 1% NP-40, 0.5% Na-deoxycholate, 0.1% SDS, 150mM NaCl, 2mM EDTA, 50Mm NaF) supplemented with protease inhibitor and phosphatase inhibitor cocktail (Gendeport, Barker, TX, USA).

Blocking agent

5% non-fat milk in Tris-buffered saline pH 7.6 containing 0.1% Tween-20.

Primary incubation

Overnight at 4°C.

Secondary incubation

1:10,000 dilution anti-rabbit secondary antibody (Sigma, Cat# 7074) for 1 h at room temperature.

Detection

The antigen–antibody complexes were detected using West-Q Pico Dura ECL Solution (Gendeport, Barker, TX, USA).
