  • PBL Assay Science (formerly PBL InterferonSource) has been manufacturing and selling interferons, cytokines, antibodies, single-analyte assay kits, cytokine multiplex ELISAs, and related reagents since 1990. PBL has changedits name to reflect the company’s growth beyond interferons to a broader range of assay-related products and services. In doing this we have not abandoned our core competency in interferon: we have simply recognized that our research, our products, and our services have moved beyond interferon into other cytokines, biomarkers, multiplexes, and biological materials.

    Our new name signifies a renewed focus on partnering with researchers to solve their most difficult problems; our goal is to grow and expand the company’s reputation as a provider of high-level Assay Science to researchers around the world.
