Cardiac & Inflammatory Biomarkers
sST2, cardiac troponin I and purified D-dimer — recombinant proteins and a plasma-derived antigen for assay development and research. Additional analytes are available on request.
Human Recombinant Soluble ST2 (sST2 / IL1RL1)
Purified recombinant soluble ST2 — the receptor for IL-33 and a key cardiac-stress / inflammatory biomarker. For assay development, calibration and research.
Recombinant Cardiac Troponin I (cTnI)
Purified recombinant human cardiac troponin I — the cornerstone myocardial-injury marker, for calibrators, controls and assay development.
Purified D-dimer Antigen
Plasma-derived D-dimer antigen — the coagulation companion to our cardiac panel, for calibrators, controls and immunoturbidimetric / lateral-flow development.
