The ImmunoVision donor program has obtained disease state plasmas of various specificities. If we do not list the specificity that you need, please contact us at 479-751-7005. ImmunoVision is continually adding new and different monospecific donors to this program. Pricing of plasma is based on volume and lot purchase. (Minimum 100ml purchase.) Each lot is one draw or unit from a single donor. An additional fee will be charged for splitting a unit or lot. The volume of each unit or lot varies, but is approximately 500 ml. As in all donor plasma, activity may vary among lots.
