Recombinant proteins and IVD raw materials for research laboratories
MEDIKAMENT supplies recombinant proteins and diagnostic raw materials — led by soluble ST2, the IL-33 receptor and cardiac-stress biomarker — to university groups and diagnostic developers across Europe and the US.
Human Recombinant Soluble ST2
Recombinant sST2 (IL1RL1 / IL-33 Receptor)
The receptor for IL-33 and a prognostic biomarker of heart failure. Supplied as a purified recombinant protein with lot-specific CoA — for immunoassay development, calibration and IL-33/ST2 research.

Water-soluble broad-spectrum preservative for multi-dose IVD reagents, calibrators and controls.
Built for the way research labs actually buy
Documentation you can file
Lot-specific CoA with every shipment, plus SDS/MSDS and HPLC/MS data on request — formatted for university procurement.
Quality & documentation →Small quantities, no drama
Evaluation and pilot quantities for individual research groups, with custom and bulk packaging when the project scales.
Ordering & shipping →Answered by a person
Technical questions on purity, buffers, reconstitution and format are answered directly, typically within one business day.
Technical support →Not all proteins are the same grade
Purity, endotoxin level, tag format and expression system change both the price and what the material can be used for. We publish the comparison openly, so you can specify deliberately instead of guessing from a label.
Specification & grade comparison
What each variable actually buys you, and why two vials with the same analyte name can differ in price by a factor of ten.
Applications
Which proteins and antigens fit which research or development question — and where our materials are genuinely the right fit.
Matching & assay support
Tell us the format and the matrix and we come back with combinations that plausibly fit — plus evaluation quantities to prove it on your bench.
