Panel de inflamación: kit HBP OEM que adopta plataformas de ensayo de quimioluminiscencia
Proteína de unión a heparina (HBP)La proteína HBP, una proteína granular derivada de neutrófilos, sirve como biomarcador de diagnóstico precoz para enfermedades infecciosas, en particular infecciones bacterianas graves. Los niveles séricos/plasmáticos de HBP aumentan significativamente en las infecciones bacterianas, mientras que las infecciones no bacterianas no provocan tal elevación.
Proteína de unión a heparina (HBP) Se aplica para la identificación temprana, la estratificación del riesgo y la evaluación del pronóstico de infecciones bacterianas graves y sepsis, así como para el diagnóstico diferencial de afecciones inflamatorias agudas y fugas vasculares localizadas inducidas por infecciones.
HBP El kit OEM utiliza un inmunoensayo tipo sándwich de dos anticuerpos y es compatible con plataformas de quimioluminiscencia. Los anticuerpos monoclonales específicos se dirigen a epítopos estructurales distintos de la molécula de HBP para capturar HBP plasmática o sérica, lo que proporciona alta sensibilidad y una especificidad excepcional sin reactividad cruzada con otras proteínas de los gránulos de neutrófilos. Calibrado con antígeno HBP recombinante de alta pureza, el ensayo ofrece resultados cuantitativos precisos, fiables y estables. Al servir como biomarcador de alerta temprana para la fuga vascular aguda y la insuficiencia orgánica, facilita la intervención clínica oportuna, la clasificación de pacientes en urgencias y en unidades de cuidados intensivos (UCI), y la monitorización dinámica de la eficacia terapéutica en enfermedades infecciosas graves.

Application Scenarios
Heparin-Binding Protein (HBP), a neutrophil-derived granule protein, serves as an early diagnostic biomarker for infectious diseases, particularly severe bacterial infections. Serum/plasma HBP levels rise significantly in bacterial infections, whereas non-bacterial infections do not induce such an elevation.
Heparin-Binding Protein (HBP) is applied for the early identification, risk stratification, and prognosis assessment of severe bacterial infections and sepsis, as well as the differential diagnosis of acute inflammatory conditions and localized infection-induced vascular leakage.

FAQ
Does HBP detect bacterial infection and sepsis earlier than PCT and CRP?
Yes. HBP is rapidly released from neutrophil secretory vesicles within 1–2 hours of bacterial stimulus—reaching peak levels up to 12–24 hours earlier than PCT or CRP, providing a crucial window for early sepsis detection and vascular leakage prediction.
Can the assay reliably differentiate severe bacterial infections from viral or non-infectious systemic inflammation?
Yes. HBP levels rise marked only in response to intact bacteria or bacterial cell wall components (e.g., LPS), remaining low or normal in viral infections, viral pneumonia, or aseptic inflammatory conditions.
