Researchers Submit Patent Application, "Pretreatment Of Plasma For Spray Drying And Storage", for Approval (USPTO 20240091667).

Researchers from Velico Medical Inc. have developed a new method for pretreating plasma for spray drying and storage. The current method of freezing plasma for storage is expensive and requires precise temperature control. The new method involves using a pretreatment solution containing a spray dry stable acidic substance (SDSAS) and amino acids to maintain the pH of the plasma during the spray drying process. This results in higher recovery and better storage stability of active plasma proteins. The spray dried plasma can be reconstituted with sterile water without the need for additional pH control measures. The patent application provides detailed information on the specific amounts and ratios of ingredients used in the pretreatment solution, as well as the equipment and processes involved in the spray drying system.
