تحديد نشاط تجلط الدم للحويصلة خارج الخلية (EV) باستخدام وقت التخثر المنشط ب EV (EV-ACT)

Executive Industry Relevance

Quantifying the procoagulant activity of extracellular vesicles (EVs) addresses a critical gap in early detection and risk assessment of hypercoagulable states across diverse disease contexts. The EV-Activated Clotting Time (EV-ACT) assay enables rapid, bedside evaluation of EV-driven coagulation, supporting mechanistic de-risking and target validation in translational research. This capability enhances predictive confidence at key inflection points in the discovery and preclinical pipeline.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables interrogation of EV-mediated coagulation pathways relevant to disease mechanisms.
• Supports biological de-risking by quantifying functional procoagulant activity of EVs.
• Facilitates target validation for interventions modulating EV release or activity.

Screening & Assay Development

• Provides a standardized, quantitative assay for assessing EV procoagulant function in plasma samples.
