Who Is Sophomer s.r.o.?

Sophomer s.r.o. is an academic startup founded by a group of people who come from both industry and academia. Their vision is to bring together two seemingly unrelated fields: immunoassays and polymer chemistry to help anyone who uses immunochemical assays in their work. One of the startup's first and widely applicable products is SophoMer™ F10, a polymer that can replace the widely used bovine serum albumin in immunochemical assays, currently a component without which the development of immunological analytics is seemingly unimaginable.


The SophoMer™ F10 is commercially available now!

What is SophoMer

What Is SophoMer™ F10?


SophoMer™ F10 is a fully synthetic material that has been developed with an ambitious goal: to replace the most commonly used nonspecific binding blocker – Bovine Serum Albumin – with a tailored fully synthetic material that meets the following criteria:

  • Is a more effective non-specific binding blocker.

  • Is a chemically defined material with minimal batch-to-batch variability.

  • Is animal component-free material.


SophoMer™ F10 was initiated to take up the challenge and support the world-leading developers of IVD immunology diagnostics. 

Highly effective synthetic polymer-based blockers of non-specific interactions

Researchers from the Institute of Macromolecular Chemistry CAS and Sophomer s.r.o. have developed highly effective synthetic polymer blockers of non-specific interactions, making it possible to replace currently used proteins of animal origin. They have just published their results in the publication below.

Four Main Benefits of SophoMer™ F10:


Tailored fully synthetic material


Chemically defined material with precise batch to batch reproducibility


Highly effective nonspecific binding blocker


Animal component-free product =
no pathogenic contaminants

How does it work

How Does SophoMer™ F10 Work?


SophoMer™ F10 can shield nonspecific non-covalent interactions in your sample solution, and block nonspecific interaction with plastic material used for analysis. In many assays, a much lower concentration of SophoMer™ F10 is required than BSA.
