Estapor® Microspheres

Many clinical laboratory tests for the detection of disease specific biomarkers, pathogens, pathogen-specific antibodies, or autoantibodies in body fluid samples rely on consistent and reproducible microspheres to create antibody-antigen interactions that result in measurable precipitating complexes.

We offer several types of Estapor® microspheres including plain, surfactant-free, small carboxyl-modified, and new IT 250 microspheres all especially designed for LTIA antibody-antigen precipitation tests.

With extremely uniform and with excellent lot-to-lot reproducibility, the microspheres are ideal for surface immobilization of molecules such as antigens, polyclonal or monoclonal antibodies, etc.
