Major companies worldwide trust our particles for research, and clinical and molecular biology applications. Our magnetic particles exhibit high binding capacity, excellent stability, low nonspecific binding, exquisite sensitivity and very slow settling rates. They are utilized in assays that test approximately 85% of the US blood supply.

Colored and fluorescent microspheres loaded with up to 25% dye by weight.  Higher intensity particles provide superior test sensitivity in qualitative and quantitative lateral flow tests.

The SpeedBeads are the newest entry in the Sera-Mag line of magnetic beads. These beads respond twice as fast to a magnetic field as our original Sera-Mag particles, and are available in Carboxylate-Modified, Streptavidin-coated and NeutrAvidin-coated versions.

Our experienced technical staff come from many scientific disciplines.  We integrate our knowledge and experience into powerful solutions and proven problem-solving for our customers.
