Description_x000D_ General description_x000D_ _x000D_ ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies._x000D_ 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._x000D_ Learn more about ZooMAb here._x000D_ Specificity_x000D_ Clone 1B21 is a ZooMab rabbit recombinant monoclonal antibody that specifically detects human von Willebrand factor._x000D_ Immunogen_x000D_ Full length purified native von Willebrand factor from human plasma._x000D_ Application_x000D_ Anti-vWF, clone 1B21 ZooMAb, Cat. No. ZRB7356, is a Rabbit Monoclonal Antibody that specifically targets human von Willebrand factor and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting._x000D_ Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected vWF in human tonsil tissue sections._x000D_ Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected vWF in HUVEC._x000D_ Target description_x000D_ von Willebrand factor (UniProt: P04275; also known as vWF) is encoded by the VWF (also known as F8VWF) gene (Gene ID:7450) in human. vWF is a multimeric plasma glycoprotein that is synthesized by endothelial cells and plays an important in the maintenance of hemostasis. It is synthesized with a signal peptide (aa 1-22), which is subsequently cleaved off in the mature form, which is cleaved into von Willebrand antigen 2 (aa 23-763) and vWF (aa 764-2813). vWF is known to promote adhesion of platelets to the sites of vascular injury by forming a molecular bridge between sub-endothelial collagen matrix and platelet-surface receptor complex GPIb-IX-V. vWF also acts as a chaperone for coagulation factor VIII, delivering it to the site of injury, stabilizing its heterodimeric structure and protecting it from premature clearance from plasma. Mutations in VWF gene are linked to von Willebrand diseases 1-3 that are common hemorrhagic disorders caused by impaired platelet aggregation. Two isoforms of vWF have been described that are produced by alternative splicing. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals._x000D_ Physical form_x000D_ 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._x000D_ Reconstitution_x000D_ 30 μg/mL after reconstitution at 25 μL. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type._x000D_ Storage and Stability_x000D_ 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.
