• Target description: Cyclic AMP-dependent transcription factor ATF-6 alpha (UniProt: P18850; also known as cAMP-dependent transcription factor ATF-6 alpha, Activating transcription factor 6 alpha, ATF6-alpha) is encoded by the ATF6 gene (Gene ID: 22926) in human. ATF6 is an endoplasmic reticulum (ER)-localized protein that is involved in transducing signals linked to ER stress. It is responsible for the correct folding, secretion, and membrane insertion of a vast majority of proteins in eukaryotic cells. Two homologous ATF6 proteins, ATF6α and ATF6β, are expressed in mammalian cells. Their C-terminal region protrudes into the ER lumen, whereas the N-terminal faces the cytosol. Although ATF6α and ATF6β display significant sequence homology, they exhibit divergent transcriptional activation domains.  ATF6α is a single-pass type II membrane protein with a cytoplasmic domain (aa 1-377), a transmembrane domain (aa 378-398), and a lumenal domain (aa 399-670). It is a homodimeric protein that can form heterodimer with ATF6β. This dimer interacts with the nuclear transcription factor Y (NF-Y) trimer through direct binding to NF-Y subunit C (NF-YC). ATF6α is a potent transcriptional activator whereas ATF6β is a poor transcriptional activator, and may even inhibit activation by ATF6α. ER stress is known to promote its processing that releases N-terminal transcription factor form that translocates into the nucleus, where it activates transcription of genes involved in unfolded protein response (UPR). Mutations in ATF6 gene are known to cause Achromatopsia 7 (ACHM7), an ocular stationary disorder due to the absence of functioning cone photoreceptors in the retina. It is characterized by total colorblindness, low visual acuity, photophobia, and nystagmus. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 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.
• Reconstitution: 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.
• Storage and Stability: 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.
• Other Notes: Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
