Procalcitonin (PCT) serves as a robust biomarker for diagnosing bacterial infections, offering high sensitivity and specificity. Serum PCT levels rise rapidly during severe systemic bacterial infections and return to baseline faster than CRP once the infection is controlled. However, localized infections typically do not induce significant PCT elevations. Consequently, PCT is widely utilized for the diagnosis and differential diagnosis of sepsis, as well as evaluating its severity and clinical progression. ★Bulk reagents are available with matching raw materials.                                             

Interleukin-6 (IL-6) is a pivotal cytokine in inflammatory and immune responses. It promotes B-cell antibody production, T-cell proliferation, and IL-2 expression, while regulating the growth and differentiation of diverse cell types. Beyond its central roles in immune regulation, acute-phase responses, and hematopoiesis, IL-6 is crucial for host defense against infections. Marked alterations in IL-6 levels closely correlate with disease activity, tumor progression, transplant rejection severity, and therapeutic efficacy.   ★Bulk reagents are available with matching raw materials.                                     

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. HBP OEM kit utilizes a two-antibody sandwich immunoassay and is applicable to chemiluminescence platforms. Specific monoclonal antibodies target distinct structural epitopes on the HBP molecule to capture plasma or serum HBP, delivering high sensitivity and exceptional specificity without cross-reactivity to other neutrophil granule proteins. Calibrated with high-purity recombinant HBP antigen, the assay provides accurate, reliable, and stable quantitative results. Serving as an early-warning biomarker for acute vascular leakage and organ failure, it supports timely clinical intervention, triage in emergency and intensive care units (ICU), and dynamic therapeutic efficacy monitoring in severe infectious diseases.   ★Bulk reagents are available with matching raw materials.                                     

Gastrin-17 (G-17) is applied for the screening, risk stratification, and auxiliary diagnosis of chronic atrophic gastritis, gastric antral mucosal atrophy, and gastric cancer, as well as the non-invasive monitoring of gastric acid status, Helicobacter pylori (H. pylori) infection, and long-term proton pump inhibitor (PPI) therapy. G17 OEM kit utilizes a two-antibody sandwich immunoassay and is applicable to chemiluminescence platforms. Specific monoclonal antibodies target distinct structural epitopes on the G-17 molecule to capture serum or plasma G-17, delivering high sensitivity and exceptional specificity without cross-reactivity to other gastrin isoforms or cholecystokinin (CCK).
