ATG4B antibody is human, mouse and rat reactive. At least two isoforms of ATG4B are known to exist, this antibody will detect only the larger isoform. ATG4B is predicted to not cross-react with other ATG4 proteins.
纯化方法
ATG4B antibody is affinity chromatography purified via peptide column.
免疫原
ATG4B antibody was raised against a 17 amino acid peptide near the carboxy terminus of human ATG4B.
The immunogen is located within the last 50 amino acids of ATG4B.
ATG4B antibody can be used for detection of ATG4B by Western blot at 1 - 2 μ,g/mL. Antibody can also be used for immunohistochemistry starting at 5 μ,g/mL. For immunofluorescence start at 20 μ,g/mL.

背景
Autophagy, the process of bulk degradation of cellular proteins through an autophagosomic-lysosomal pathway is important for normal growth control and may be defective in tumor cells. It is involved in the preservation of cellular nutrients under starvation conditions as well as the normal turnover of cytosolic components (1,2). ATG4B, also known as AUTL1, is one of four mammalian orthologs of the yeast ATG4 protein, all four are cysteine proteases (3). ATG4 is required for ATG8 conjugation to phosphatidylethanolamine on autophagosomal membranes. In mammals, each ATG4 homolog shows a selective preference for the ATG8 homologs (4). ATG4B has been found to be a novel protective protein in inflammatory colitis (5).
