Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E.coli-derived mouse VWF recombinant protein (Position: M1304-E1452). (reported region: M1304-E1452).
- Molecular weight context: reported MW: 309 kDa; calculated MW: 309269 MW
- Reactivity: Mouse,Rat
- Applications: IF, IHC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
von Willebrand factor; von Willebrand factor. Von Willebrand factor (VWF) is a blood glycoprotein involved in hemostasis. It is mapped to 12p13.31. The VWF gene encodes von Willebrand factor (VWF), a large multimeric glycoprotein that plays a central role in the blood coagulation system, serving both as a major mediator of platelet-vessel wall interaction and platelet adhesion, and as a carrier for coagulation factor VIII. VWF released from endothelial cell Weibel-Palade bodies bound particularly avidly to the extracellular matrix. VWF deficiency or dysfunction (von Willebrand disease) leads to a bleeding tendency, which is most apparent in tissues having high blood flow shear in narrow vessels. Functional note: 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. . Reported localization: Secreted . Secreted, extracellular space, extracellular matrix . Localized to storage granules. . Expression/tissue context: Plasma. Expressed in liver. .
Research relevance and current trends
- Serum Proteins: Researchers commonly examine how VWF (von Willebrand factor) relates to this theme using model systems and orthogonal readouts.
- Stem Cells: Researchers commonly examine how VWF (von Willebrand factor) relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative VWF (von Willebrand factor) levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of VWF (von Willebrand factor) across tissue regions and cell types using matched controls.
- IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins
- Family / similarity context: Contains 1 CTCK (C-terminal cystine knot-like) domain.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
