Thermo Fisher Scientific Inc., the world leader in serving sciences, announces its first ever NeutrAvidin coated magnetic particles – Thermo Scientific Seradyn Sera-Mag^® SpeedBeads^™ NeutrAvidin magnetic particles. With the development of these particles, Thermo Fisher is continuing to establish itself as a world leader in manufacturing and supplying microparticles.

These particles have a biotin-binding capacity of 3500 to 4500 pmol/mg and offer an alternative to our Streptavidin-coated SpeedBeads. When non-specific binding is problematic, the NeutrAvidin protein used for our NeutrAvidin SpeedBeads contains no carbohydrates and has a near-neutral isoelectric point of 6.3. These features provide very low non-specific binding and broader utility in a variety of applications.

“The NeutrAvidin SpeedBeads further complement our existing line of Sera-Mag particles," said Thermo Fisher Scientific Director of Particle Technology Rick Galloway. "These particles have a faster magnetic response time in viscous cell lysates with lower non-specific binding. These characteristics are critical when used for diagnostic and molecular biology applications."

Thermo Scientific Seradyn microparticles are manufactured in our ISO-13485 certified facility following a computer-aided design. You are assured of a superior product. Our microparticles feature high sensitivity and excellent reproducibility, yielding a high binding capacity while keeping nonspecific binding low and maintaining long-term stability. Because we manufacture the particles, extensive information about their characteristics and functionality is made available to you. We provide concrete data, backed by years of clinical applications research, which will take the mystery out of working with microparticles.

The NeutrAvidin SpeedBeads are now available for sale through Thermo Fisher Scientific. For more information call 1-866-737-2396 or 1-317-610-3800 or visit www.thermo.com/seradyn.
