Pentastarch Solution

Simplify the cryopreservation process with an extracellular protective agent that safeguards cells during the freeze/thaw process

Leading medical solutions manufacturer Preservation Solutions, Inc. developed the PSI Pentastarch Solution with the unique needs of cell preservation centers in mind. The PSI Pentastarch Solution acts as an extracellular protectant when mixed with cells and intracellular cryopreservatives during the freeze/thaw process.

Designed to support the delicate cryopreservation freeze/thaw cycle and aid in cellular preservation, PSI Pentastarch Solution offers multiple positive attributes and clinical benefits:
