  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

VWF / Von Willebrand Factor antibody was raised against factor VIII complex.
Reacts with human von Willebrand's factor (also known as Factor VIII related antigen) in both plasma and tissues. Does not have anti-coagulant activity.
Immunohistochemistry: LS-B4034 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for LS-B4034 was determined to be 10 ug/ml.


PBS, pH 7.4, 0.2% BSA, 0.1% sodium azide, 50% glycerol.
+4°C or -20°C, Avoid repeated freezing and thawing.
For research use only.

About VWF / Von Willebrand Factor

P04275 NM_000552 NP_000543.2

VWF Antibody, Coagulation factor VIII VWF Antibody, F8VWF Antibody, VWD Antibody, Von Willebrand factor Antibody

Important in the maintenance of hemostasis, it promotes 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. 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.
