Will the magnetic beads (SIGMA-ALORICH; ANTI-FLAG M2 Magnetic Beads; Catalog Number:M8823) that suspended in 50% glycerol be freezed at -20 ℃? In my oponion, stored in glycerol is to avoid freeze, in order to decrease damage to the magnetic beads surface? Because the beads were borrowed from other lab, I have no idea about why it will be freezed? Does anyone who has ever used it? Is that okay to use? Really thanks a lot!
