Title: Barbara Schnabel-Preikstas: Innovator in Plant Cell Cryopreservation

Introduction

Barbara Schnabel-Preikstas is a prominent inventor based in Ithaca, NY (US). She has made significant contributions to the field of plant cell cryopreservation, holding 2 patents that focus on innovative methods for preserving plant cells.

Latest Patents

Her latest patents detail methods for cryopreserving plant cells and recovering viable cells from both long and short-term cryopreservation. The processes involve growing plant cells in culture, pretreating them with a cryoprotective agent and stabilizer, and acclimating them to reduced temperatures. The cells are then loaded with agents such as DMSO, propylene glycol, or polyethylene glycol. Vitrification solutions are used to ensure that the cells retain less than about 20% water content, allowing them to be frozen for extended periods without altering their genotypic or phenotypic characteristics. Additionally, methods for lyophilizing cells prior to vitrification are included, which effectively removes a significant portion of the plant cell's water content.

Career Highlights

Barbara is associated with Phyton Corporation, where she continues to advance her research in plant cell preservation. Her work has been instrumental in developing techniques that enhance the viability of plant cells after cryopreservation.
