Cardiac & Inflammatory Biomarkers
sST2, cardiac troponin I and purified D-dimer — recombinant proteins and a serum-derived native 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.
Infectious Disease Antigens
Recombinant M. tuberculosis antigens — CFP-10, ESAT-6 and the TB-16/38 fusion panel — purified and documented for tuberculosis assay development and research.
Recombinant TB CFP-10 Antigen
Purified recombinant CFP-10 — the M. tuberculosis-specific RD1 antigen at the centre of IGRA diagnostics. For TB assay development, calibration and research.
Recombinant TB ESAT-6 Antigen
Purified recombinant ESAT-6 — the other half of the RD1 antigen pair, central to interferon-gamma release assays. For TB assay development and research.
Recombinant TB-16 & TB-38 Fusion Antigen
Recombinant fusion of the 16 kDa and 38 kDa TB antigens — established antibody-detection targets supplied as one documented reagent.
Recombinant TB-16, TB-38 & ESAT-6 Fusion Antigen
Recombinant triple fusion of the 16 kDa, 38 kDa and ESAT-6 TB antigens — one documented reagent covering three targets.
Research Reagents
High-purity biological buffers and a broad-spectrum preservative system to keep your assays stable, reproducible and shelf-stable.
TRIS Base and TRIS-HCl, High-Purity Biological Buffer
High-purity TRIS buffers for IVD reagent formulation, protein purification and molecular biology.
HEPES, High-Purity Biological Buffer
High-purity zwitterionic buffer for cell culture, enzyme assays and diagnostic reagent formulation.
MES Monohydrate, High-Purity Biological Buffer
High-purity low-pH buffer (pKa 6.1) for enzyme and conjugation chemistry.
Broad-Spectrum IVD Reagent Preservative
Water-soluble broad-spectrum preservative for multi-dose IVD reagents, calibrators and controls.
Cannot find your analyte?
We supply a wider range of recombinant proteins, antigens and antibodies than listed here — including custom expression and bulk quantities for diagnostic development.
Why this catalogue is short — and what that means for you
A page of 5,000 analytes is easy to publish and impossible to stand behind. We list what we can ship with a lot-specific certificate and confirmed specifications, and handle the rest to order.
Listed lines
Quoted from stock or current production, with representative specifications published and a lot-specific CoA on shipment. These are the lines we can usually supply for evaluation quickly.
Sourced to order
Analytes, antigens and antibodies we can obtain against your specification, with availability and lead time confirmed per enquiry rather than promised on a page.
Not served
Requirements we cannot meet: GMP-released components, finished diagnostic kits, therapeutic-grade material. We say so at the first enquiry instead of two emails later.
Starting from the catalogue, or from the application?
Both routes are fine, and they converge quickly. If you already know the analyte, the specification guide explains what purity, endotoxin and format actually change for your assay. If you know the application but not the specification, describe it and we will recommend material rather than sell you the nearest bottle on the shelf.
A note on the search box above: it filters the listed catalogue only. If nothing matches, the analyte may still be obtainable — the additional analytes page explains how to-order enquiries work, and a one-line enquiry is usually faster than searching.
