In Vitro Diagnostic (IVD) Reagents

Develop and calibrate sensitive in vitro diagnostics (IVDs) and assay kits with highly pure, highly active native proteins.

From Alzheimer’s to cardiovascular and autoimmune conditions, our proteins enable assays that improve decision-making across the healthcare continuum.

High-yield production, lot-to-lot consistency, and audit-ready documentation ensure reliable performance and smooth regulatory reviews.

Experience the Athens Standard:

Preserved native structure and reproducible activity
Comprehensive lot-specific testing and rigorous QC standards
Transparent supply chain and in-house manufacturing
Customizable form, buffers, and more
Immunogen-grade proteins (≥98% purity) for polyclonal antibody production

Native activity. Trusted purity. Reliable results.

Athens IVD Reagents in Action

From fueling biomarker research and validation to enabling sensitive immunoassays, reliable native proteins allow you to elevate diagnostic science across diverse conditions.

R&D teams worldwide are using our high-purity proteins to advance diagnostics:

Breath-based biosensors¹ for lower respiratory tract infection detection
Rapid ELISA assays² for accurate measurement of lipoprotein(a), an important cardiovascular risk factor
In vivo theranostics³ development for Alzheimer’s disease
High-throughput clinical chemistry formats, including nephelometry and turbidimetry

In recent years, Athens’ proteins have enabled investigations into biomarkers, like butyrylcholinesterase (BChE)1,3—a potential indicator of sudden infant death syndrome (SIDS) and a promising drug target for Alzheimer’s disease treatment.

With Athens, your R&D teams have a dependable foundation for assays, biosensors, calibrators, controls, and custom antibody production.

Here's how:

Native structure and activity, enabling biologically relevant assays and antibody generation
High purity and reproducibility, giving teams confidence in signal stability and reducing lot-to-lot variability
High yields and batch reservations from single or pooled donors, supporting long-term programs
Optimized purification processes that maintain form, fit, and function from mg to kg, simplifying revalidation and ensuring IVD raw material consistency at every scale

Our experts work closely with you to help solve complex technical problems and deliver tailored solutions that stand up to today’s clinical chemistry challenges.
