Post-thaw cell recovery of cell monolayers. (A) Schematic
of the
monolayer cryopreservation process. (B) Percentage cell recovery of
A549 (n = 4), HepG2 (n = 2), and
Caco-2 (n = 2) cell monolayers following cryopreservation
with 10% v/v DMSO (white bar) or 10% v/v DMSO and 40 mg mL–1 polyampholyte (grey bar). (C) Percentage cell recovery of A549 (white
bar), HepG2 (grey bar), and Caco-2 (dark grey bar) cell monolayers
in selected individual wells (filled in black in the 24-well plate
schematic) following cryopreservation in 10% v/v DMSO and 40 mg mL–1 polyampholyte. Data is presented by average percentage
cell recovery ± SEM of n independent repeats
(ANOVA, Tukey PostHoc; *p ≤ 0.05, **p ≤ 0.01).
