Anti-HABP2 Antibody

HABP2 encodes Hyaluronan Binding Protein 2, a circulating serine protease also called FSAP (Factor VII-Activating Protease) that participates in coagulation cascade activation and extracellular hyaluronan turnover. Antibodies.com supplies this rabbit polyclonal reagent for laboratories profiling HABP2 expression in vascular biology, fibrosis, and tumor microenvironment studies.

The antibody is provided at 100 µl volume, unconjugated, and formulated at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol as a cryoprotectant. Store refrigerated at -20 °C and avoid repeated freeze-thaw cycles; working aliquots kept at 4 °C are stable for short-term use. Reactivity is reported for human, mouse, and rat samples, and the polyclonal host format supports recognition across multiple epitopes on the target protein.

Validated uses include Western blot on cell and tissue lysates, immunohistochemistry on formalin-fixed paraffin-embedded sections, and immunofluorescence on cultured cells or frozen tissue. HABP2 has been documented in hepatocytes, vascular smooth muscle, and selected tumor cell populations, making this reagent relevant to liver, vascular, and oncology research programs. Researchers often pair this polyclonal with housekeeping markers to interpret band identity on Western blots and to localize FSAP within tissue architecture.
