You can, but we strongly advise avoiding refreezing. Instead, plan your workflow to thaw once and allocate cells immediately into parallel conditions (or expand via differentiation where appropriate). The product notes explicitly caution against repeated freezing and thawing.
Have liquid nitrogen storage ready. Upon receipt, move vials directly from dry ice to liquid nitrogen (-150°C to -190°C) unless you are thawing right away. This is stated as a handling requirement, and it's one of the most common points where labs inadvertently lose performance.
The page provides access to a datasheet, and key product attributes (species, source, format, QC contaminants, shipping, handling notes, and size) are clearly listed-these are typically what QA teams need for study records and material traceability.
