Cancer

Tumor biology involves proteases, inhibitors and matrix proteins in constant interplay. Studying these systems—or developing therapeutics that target them—requires cancer reagents that reflect their native complexity.

Athens cancer-linked proteins are purified from human sources to preserve the structure, activity, and post-translational modifications that define protein function in the tumor microenvironment.

Our portfolio spans cathepsins, protease inhibitors, matrix proteins, and cell culture supplements – supporting oncology research from discovery through clinical development.

Experience the Athens Standard:

  • ≥98% purity for critical applications
  • Lot-specific CoAs with activity and purity data
  • 95% same- or next-day shipping

Native activity. Trusted purity. Reliable results.

Native Proteins for Oncology Research

Cancer research spans mechanistic studies of tumor biology, biomarker discovery, diagnostic production, and therapeutic development. Athens provides native human proteins that support work across this spectrum.

Our cancer reagents include proteases implicated in invasion and metastasis, protease inhibitors that regulate tumor progression, and matrix proteins involved in adhesion and angiogenesis—all with native activity preserved.

What sets Athens apart for cancer research:

Tumor-associated proteases – Cathepsins B, D, H, and L from human liver, plus plasmin, plasminogen, and kallikrein from human plasma. Native enzymatic activity verified for functional studies of invasion, metastasis, and extracellular matrix remodeling.

Protease inhibitors and regulatory proteins – Alpha-2 Macroglobulin, Alpha-1 Antitrypsin, and Inter-Alpha Inhibitor Protein for studying the protease-antiprotease balance that influences tumor progression.

Extracellular matrix proteins – Vitronectin and Thrombospondin for research on cell adhesion, migration, and the tumor microenvironment.

Immunoglobulins for cancer diagnostics and research – Complete IgG subclass panel, IgA, IgM, and IgE for assay development, controls, and cancer biomarker research.

Cell culture supplements – Transferrin, Albumin, and lipoproteins for maintaining cancer cell lines and producing therapeutic monoclonal antibodies.

Trusted in Cancer Research

Athens proteins support oncology labs worldwide—from mechanistic studies to therapeutic development.
