Using an age-defined donor (Age: 40) strengthens cohort control and makes it easier to justify biological comparability-especially when you plan to test multiple stimuli, compounds, or timepoints and want to reduce background variability.
The page explicitly cautions that repeated freezing and thawing is not recommended. Best practice is to keep vials continuously cryogenic until use, avoiding partial thaw/refreeze events that can impair recovery and functional responsiveness.
The vial contains 5×10^7 cells, enabling large-scale differentiation and multi-endpoint testing (e.g., polarization panels + repeated cytokine sampling + omics) while staying within a single vial's source for consistency.
