Anti-ATG3 Antibody, clone 3M21 ZooMAb^® Rabbit Monoclonal

Ubiquitin-like-conjugating enzyme ATG3 (UniProt: Q9NT62; EC:2.3.2.-; also known as Autophagy-related protein 3 (APG3-like; hApg3), Protein PC3-96) is encoded by the ATG3 (also known as APG3, APG3L) gene (Gene ID: 64422) in human. ATG3 is characterized by a conserved structure typical of E2 ubiquitin-conjugating enzymes, which includes a catalytic cysteine residue essential for its enzymatic activity. ATG3 functions primarily as an E2-like enzyme in the autophagy pathway. It is responsible for the conjugation of ATG8 (LC3 in mammals) to phosphatidylethanolamine (PE) on autophagic membranes. This lipidation process is crucial for the expansion and closure of the autophagosome, a key step in autophagy. ATG3 works in conjunction with ATG7, an E1-like enzyme, to transfer ATG8 to the membrane. Mutations or dysregulation of ATG3 can contribute to various diseases, including neurodegenerative diseases, cancer, and infectious diseases. In cancer altered autophagy can affect tumor progression and response to therapy. This ZooMAb^® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone 3M21 is a ZooMAb^® rabbit recombinant monoclonal antibody that detects ATG3. It targets an epitope within 18 amino acids from the N-terminal half.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
