Used in biomedical research to quantify thrombospondin-1 (TSP-1) levels in rat platelet samples. Enables investigation of platelet activation and release during thrombotic events. Supports studies on angiogenesis, wound healing, and vascular remodeling due to TSP-1's role in cell adhesion and signaling. Commonly applied in preclinical models of cardiovascular disease, inflammation, and cancer metastasis. Provides a reliable, sensitive method for detecting TSP-1 in serum, plasma, and cell culture supernatants. Facilitates high-throughput screening in drug development targeting platelet-related pathways.
