Improved iPSC Cryopreservation with Optibumin 25: Enhanced Viability, Expansion, and Pluripotency

By

Audio Summary: Improved iPSC Cryopreservation with Optibumin 25 Overview This application note evaluates the performance of Optibumin® 25, a recombinant, animal-origin-free human serum albumin (rHSA), in the cryopreservation of human induced pluripotent stem cells (iPSCs). The study demonstrates that Optibumin 25 enables a significant reduction in DMSO concentration while improving post-thaw viability, expansion, and pluripotency. …

Superior Cryopreservation of T Cells in Low-DMSO, Animal-Origin-Free Formulation Using Optibumin 25 and PentaHibe Base

By

Overview This application note presents a defined, animal-origin-free (AOF) cryopreservation strategy addressing the limitations of high-DMSO and serum-derived components. The formulation—10% PentaHibe Base, 2% DMSO, and 4% Optibumin 25—was tested in CAR-T–mimicking workflows using healthy donor T cells. PentaHibe Base is a non-penetrating, carbohydrate-based cryoprotectant derived from pentaisomaltose, a patented subfraction of Dextran 1 with …
