Is PLTMax® xeno-free?

No. We add a small amount of heparin. Keep in mind that this is pharmaceutical grade heparin. It is a widely prescribed and safe drug. So far, we have not had any commentary from any regulatory agency suggesting that the addition of heparin is of any significant concern. We do have an alternative without heparin, but heparin addition is the standard and has been widely used in many, if not most, of the clinical protocols.
