Product Overview
VWF polyclonal antibody detects endogenous levels of VWF protein.
Von Willebrand disease is a congenital bleeding disorder caused by defects in the von Willebrand factor protein (VWF). VWF is a multimeric glycoprotein that is found in endothelial cells, plasma and platelets, and it is involved in the coagulation of blood at injury sites. VWF acts as a carrier protein for Factor VIII, a cofactor required for coagulation, and it promotes platelet adhesion and aggregation. Several factors are known to stimulate the binding of VWF to platelets, including glycoprotein 1b, ristocetin, botrocetin, collagen, sulphatides and heparin.

This antibody has been validated for IHC. Always refer to the product datasheet for recommended dilution ranges and appropriate positive control samples for each application type.
Validated reactivity has been confirmed for Human, Mouse, Rat. Cross-reactivity with additional species may exist based on sequence homology but has not been confirmed by the manufacturer. For unlisted species, we recommend running a preliminary validation experiment.
This antibody was raised in Rabbit. For indirect detection (WB, IHC, IF), select an anti-Rabbit secondary antibody that matches the isotype. For direct detection, check the variant selector for conjugated formats. Confirm secondary antibody compatibility before ordering.

Please refer to the storage conditions on the product label and datasheet. As a general best practice: upon receipt, aliquot into single-use volumes to minimize freeze-thaw cycling, which can progressively reduce antibody performance and lead to aggregation.
Validated reactivity covers Human, Mouse, Rat samples. Performance can vary across different cell lines and tissue types depending on target antigen expression levels and epitope accessibility. We recommend verifying target expression in your specific model system using a known positive control before proceeding to experimental samples.
