Infectious Disease & Diagnostics

Diagnostic development is unforgiving. A calibrator that drifts between lots can invalidate months of work. A control that doesn't behave like patient samples can mask assay failures. Athens proteins eliminate these variables.
Our proteins are purified from native human plasma, neutrophils, and other tissues – preserving the glycosylation, structure, and activity that define how these molecules behave in clinical samples. For IVD manufacturers, this means calibrators and controls that reflect real biology.

What sets Athens apart for infectious disease diagnostics:

Acute phase proteins for sepsis and infection markers – CRP, haptoglobin, ceruloplasmin, and Alpha-1 Acid Glycoprotein for inflammation and infection response monitoring.
Antimicrobial proteins with native activity – Lactoferrin, defensins, lysozyme, and BPI (bactericidal permeability-increasing protein) purified from neutrophils and milk with antimicrobial function intact.
Complement components – C3c, C4c, and C5 for assays measuring complement activation in infectious and inflammatory states.
Immunoglobulins for assay development – IgG, IgA, IgM, and subclasses for calibrators, positive controls, and interference testing in serological assays.
Athens diagnostic reagents are trusted by IVD manufacturers worldwide, supporting everything from traditional immunoassays to next-generation biosensor platforms.
