Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived rat PF4 recombinant protein (Position: V30-S105). (reported region: V30-S105).
- Molecular weight context: reported MW: 11 kDa; calculated MW: nan
- Reactivity: Mouse,Rat
- Applications: ELISA, 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
platelet factor 4. Platelet factor 4 (PF4) is a small cytokine belonging to the CXC chemokine family that is also known as chemokine (C-X-C motif) ligand 4 (CXCL4). By in situ hybridization, the CXCL4 gene is mapped to chromosome 4q12-q21. Its major physiologic role appears to be neutralization of heparin-like molecules on the endothelial surface of blood vessels, thereby inhibiting local antithrombin III activity and promoting coagulation. As a strong chemoattractant for neutrophils and fibroblasts, PF4 probably has a role in inflammation and wound repair. Functional note: Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation. Reported localization: Secreted.
Research relevance and current trends
- Atherosclerosis: Researchers commonly examine how Pf4 relates to this theme using model systems and orthogonal readouts.
- Cardiovascular: Researchers commonly examine how Pf4 relates to this theme using model systems and orthogonal readouts.
- Chemokines: Researchers commonly examine how Pf4 relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative Pf4 levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of Pf4 across tissue regions and cell types using matched controls.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- 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.
