• Target description: Clusterin (UniProt: P10909; also known as Aging-associated gene 4 protein, Apolipoprotein J, Apo-J, Complement cytolysis inhibitor, CLI, Complement-associated protein SP-40,40, Ku70-binding protein 1, NA1/NA2, Sulfated glycoprotein 2, SGP-2, Testosterone-repressed prostate message 2, TRPM-2) is encoded by the CLU (also known as APOJ, CLI, KUB1, AAG4) gene (Gene ID: 1191) in human. Clusterin is a ubiquitously expressed protein that functions as extracellular chaperone that prevents aggregation of non-native proteins. It also prevents stress-induced aggregation of plasma proteins. Clusterin is synthesized with a signal peptide (aa 1-22), which is subsequently cleaved off to generate the mature form that can be proteolytically cleaved into a b-chain (aa 23-227) and an a-chain (aa 228-449). However, proteolytic cleavage is not necessary for its chaperone activity. Six different isoforms of Clusterin have been described that are produced by alternative splicing. Isoform 1 is shown to retro-translocate from the secretory compartments to the cytosol upon cellular stress, but isoforms 4 and 6 retain their cytoplasmic localization in stressed and unstressed cell. It maintains partially unfolded proteins in a state appropriate for subsequent refolding by other chaperones, such as HSPA8/HSC70, but does not refold proteins by itself. Clusterin is reported to bind to Amyloid b-peptides and alters their aggregation and promote their clearance, suggesting its neuroprotective role. 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 mouse 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: 30 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.
