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

Calnexin (UniProt: P27824; also known as IP90, Major histocompatibility complex class I antigen-binding protein p88, p90) is encoded by the CANX gene (Gene ID: 821) in human. Calnexin is a member of the calreticulin family of proteins. It is a well-conserved, single-pass type I membrane protein that serves as calcium binding, endoplasmic reticulum (ER) resident chaperone protein. It associates with newly synthesized, incompletely folded monomeric glycoproteins and promotes their correct folding prior to secretion. It is also reported to target misfolded proteins for degradation. It is anchored to the ER membrane by a transmembrane domain. Calnexin associates with partial T-cell antigen receptor complexes that escape the ER of immature thymocytes and may, therefore, function as a signaling complex regulating thymocyte maturation. Calnexin is synthesized with a signal peptide of 20 amino acids, which is subsequently cleaved off to generate the mature form that has a lumenal domain (aa 21-481), a short transmembrane domain (aa 482-502) and a cytoplasmic domain (aa 503-592). Three isoforms of calnexin have been described that are generated by alternative splicing. Calnexin is shown to be phosphorylated at serine 564 by MAPK3/ERK1, which increases its association with ribosomes. 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 with 5% Trehalose. Normal appearance is 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.


30 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.
