Why create another option? \"Balancing pulling speed, size uniformity and settling
rates is challenging when developing magnetic beads,\" according to Chad Owen, Vice
President of Polysciences, Inc. - Particles Division. \"ProMag™ separates more
rapidly than other uniform magnetic beads, yet does not settle too quickly.\"

For a limited time, Polysciences, Inc. is offering a trial size of the COOH version
of ProMag™. Contact Customer Service for special pricing.
