Can I freeze the PTMScan® HS Magnetic Immunoaffinity Beads?

The PTMScan HS Magnetic Immunoaffinity Beads should not be frozen. We recommend storing this product at 4C. However, we have performed functional testing by IAP and subsequent mass spec analysis after 1X round of freeze thaws and found that the beads performed as expected. If the beads are accidentally frozen and thawed once, they should be fine to use, but we first recommend submitting a technical support inquiry to discuss this with a CST product scientist.
