What makes the PBL products different?

With three decades of assay manufacturing specialising in interferon assay kit developments, PBLs immunoassay products can empower researchers to unravel the complexities of the immune system, to clearly understand the underlying disease mechanisms, host-pathogen interactions, and immunological responses. PBL’s immunoassay kits enable researchers to characterise patient populations thereby tailoring treatments based on individual biomarker profiles.

  • PBL’s Elisa assays are tested for real – world application using healthy donors and autoimmune patient samples to develop high throughput assays.
  • With their highly specific and sensitive performance, these assays can detect low levels of endogenous IFNs and other cytokines in high complex diseases matrix samples.
  • Focused to always provide best in class assessment for all Types of interferons, they are one of the best manufacturers that can produce Lower Limit of Quantitation (LLOQ) for endogenous level for the cytokines from 1pg/ml compared to competitors at 15pg/ml.

Optimized for Real-World Performance

Facilitate the transition from pre-clinical research to clinical studies with ELISAs suitable for cell & tissue culture work, mouse models, as well as healthy donor and autoimmune patient samples.

  • All-Subtype detection at market-leading LLOQS (IFN-alpha)
  • Tested in autoimmune diseases sera
  • Independent CRO validatedLevels of IFN-beta quantified in healthy donor, influenza patient, and multiple sclerosis (MS) patient sera

Pharmaceutical and biotechnology researchers can rely on PBL's interferon and cytokine products to facilitate drug discovery and development. Precise measurement of these immune system proteins aids in evaluating potential therapeutic candidates and assessing their effects on the immune response

  • With numerous high - impact journal publication and validated by independent CROs, these products can facilitate the transition from pre-clinical to clinical studies as they are developed based on real-world patient donor samples 

PBL's also provides biomarker testing services that can help contribute to accurate disease diagnosis and patient stratification. By leveraging their solutions, researchers can identify and measure biomarkers for disease progression and treatment efficacy insights. 

Choosing PBL Assay Science as your biomarker solution provider through 2BScientific unlocks groundbreaking discoveries, improved patient care, and the advancement of scientific knowledge.
