Where our materials are used
The same analyte can serve several very different purposes, and the specification that suits one will not suit another. These are the four areas our catalog is built around — if your application is not listed, describe it and we will tell you honestly whether we are the right supplier for it.
Cardiovascular research
Cardiac stress, myocardial injury and coagulation readouts for heart-failure and acute-coronary research, run individually or as a panel.
Inflammation & immunology
Acute-phase and cytokine targets, plus the IL-33/ST2 axis where sST2 functions as a decoy receptor rather than a cardiac readout alone.
IVD assay development
Three distinct roles, three different specifications: antigen for the reaction, calibrator for the curve, control for the run.
Cell-based & signalling studies
Where live cells are involved, endotoxin becomes the deciding specification rather than a footnote — ask for the < 0.1 EU/µg grade. For binding and structural work the deciding variables are conformation and glycosylation rather than endotoxin.
Rather start from the specification?
If you already know the purity, endotoxin and format you need, the comparison page explains what each variable buys you before you talk to anyone.
Matching the material to the application
The same analyte name can hide several different products. The table below maps the applications above to the materials in our catalog and the specification that actually changes with the use.
| Application | Material | What to specify in your enquiry |
|---|---|---|
| sST2 immunoassay development | Human recombinant soluble ST2 plus matched mouse monoclonals | Role of each component — capture, detection or calibrator. Capture and labelling antibodies are supplied unconjugated so the pairing chemistry stays yours. |
| Cardiac injury assays (cTnI) | Recombinant cardiac troponin I | Recombinant antigen for calibrator and immunogen use; state whether matrix comparability to patient samples matters for your curve. |
| Thrombosis and fibrinolysis studies | Purified D-dimer antigen | Antigen derived from human serum for coating or calibration; goat and rabbit polyclonals are available as pairing partners. |
| Inflammation readouts | Recombinant CRP | Purity grade and endotoxin level if any cell-based work is downstream of the assay. |
| Assay buffer preparation | TRIS buffer and related biological buffers | Grade, concentration and pH range; tell us the assay context so preservative-free formats are quoted where conjugation follows. |
Representative specifications for the core lines — catalog numbers, lots, concentrations and buffers — are published on the published specifications page, and a side-by-side view is in the specification guide. The lot shipped to you is always described by its own Certificate of Analysis.
