October 2010 – Bangs Laboratories is proud to announce the addition of ProMag™ 1µm magnetic microspheres to its product line. Like its 3µm counterpart, 1µm ProMag™ boasts stringent size uniformity, fast and uniform separations, high coating capacity, and low nonspecific binding of proteins. The smaller 1µm size offers far greater surface area per unit weight, which may present a considerable advantage for the purification of biomolecules or capture of low-concentration targets.
