Rapid intracellular bioprotection of betaine.
(A) Post-thaw efficiency of Hela cells after incubation for different periods in medium containing 0.5% (blue), 1% (red), 2%, (green) of betaine. Post-thaw survival efficiency of (B) GLC-82 cells, (C) Hela cells and (D) MCF-10 cells after cryopreservation using betaine (red), trehalose (blue), and trehalose + 10% DMSO (purple) with ultrarapid freezing protocol. Value = mean ± standard deviation, n ≥ 3.
