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.
Clone 1F16 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Calreticulin. It targets an epitope within 21 amino acids from the C-terminal half.
KLH-conjugated linear peptide corresponding to 21 amino acids from the C-terminal half of human Calreticulin.

Calreticulin (UniProt: P27797; also known as CRP55, Calregulin, Endoplasmic reticulum resident protein 60, ERp60, HACBP, grp60) is encoded by the CALR (also known as CRTC) gene (Gene ID: 811) in human. Calreticulin is a highly conserved, monomeric, endoplasmic reticulum protein that is synthesized with a signal peptide (aa 1-17), which is subsequently cleaved off to generate the mature form (aa 18-417). It serves as a calcium-binding chaperone that promotes folding, oligomeric assembly, and quality control in the endoplasmic reticulum via the calreticulin/calnexin cycle. It consists of three distinct domains: An N-terminal lectin-like globular domain that is required for its interaction with integrins and it contains a steroid receptor-like DNA-binding site that is involved in chaperone functions; a second domain is a central proline-rich domain that forms an elongated arm-like structure and has high-affinity and low-capacity for calcium-binding and participates in its chaperone activity. The third domain is a highly acidic, localized in the C-terminal region, displays low-affinity and high-capacity for Ca2+ binding and is involved in calcium -buffering functions of calreticulin. It also has a KDEL motif at the C-terminus that is responsible for calreticulin retrieval from the Golgi apparatus to the endoplasmic reticulum. Cancer cells undergoing immunogenic cell death are reported to expose calreticulin on their surface, which promotes the uptake of dead cells by phagocytes. Mutations leading to loss-of-function of CALR gene promote oncogenesis by impairing homeostasis in healthy cells and hamper natural and therapy-driven immunosurveillance. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.
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.
