Value-added Deliverables
① 200ug * antigen (positive control); ② 1ml * Pre-immune serum (negative control);
Quality Guarantee
① Antibody purity can be guaranteed above 90% by SDS-PAGE detection; ② ELISA titer can be guaranteed 1: 64,000; ③ WB validation with antigen can be guaranteed positive;
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.
