ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Target description

Prominin-1 (UniProt: O43490; also known as Antigen AC133, Prominin-like protein 1, CD133) is encoded by the PROM1 (also known as PROML1, MSTP061) gene (Gene ID: 8842) in human. CD133 (Prominin-1) is multi-pass cell-surface glycoprotein that plays a role in cell differentiation, proliferation and apoptosis. It binds cholesterol in cholesterol-containing plasma membrane microdomains and may play a role in the organization of the apical plasma membrane in epithelial cells. During early retinal development CD133 acts as a key regulator of disk morphogenesis. Defects in PROM1 gene are known to cause retinitis pigmentosa, cone-rod dystrophy, and retinal macular dystrophy 2. Higher levels of CD133 have been reported in several cancer cell types, including various leukemias, retinoblastomas, glioblastomas, and kidney carcinomas. Higher levels of CD133 are also observed in pancreatic, gastric, colorectal, and hepatocellular cancers. It is also considered as a marker of stem cells in the adult small intestine that are susceptible to transformation into tumors retaining a fraction of mutant Prom1+ tumor cells. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Zhu, L., et al. (2009). Nature 477 (7229); 603-607).

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. 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. 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.
