Enter your email to join Dr. Peter Stenlund as he reveals BOLD’s 50x sensitivity boost!

What You’ll Learn in This Webinar Recording
- The critical role of cytokines in immunology research
- How BOLD technology supercharges standard immunoassays
- Case study: Achieving a 50x lower limit of detection for IL-4
- Step-by-step guide to integrating BOLD into your assays
- Future applications for drug discovery and diagnostics
Peter walks you through optimizing a human IL-4 ELISA, achieving a limit of detection (LOD) of 0.040 pg/mL—nearly 50x better than the standard 1.9 pg/mL. This breakthrough not only accelerates biomarker discovery but also paves the way for less invasive testing and improved therapeutic monitoring.
About Peter Stenlund
Dr. Peter Stenlund is an experienced protein chemist with a PhD in biochemistry from Umeå university. Briefly, from that point forward to his present position at Cavidi AB, he has been employed as a senior lecturer, as a post-doctoral scientist in USA, as a development scientist at Biacore and as a senior scientist at Octapharma and Galderma. His work has focused on analytical development aimed for characterization and release of protein drugs.


About Exazym®
Exazym® is an add-on immunoassay reagent kit that provides attomole-level detection of low-abundance biomarkers using standard immunoassay workflows. It is based on a new detection method called Binding Oligo Ladder Detection, or BOLD for short.
