Methodology:
Optical Mapping
Instructions:
Protect specimen by wrapping each individual tube and T25 flask in
bubble-wrap or toweling. Place specimens into Styrofoam container
with bubble wrap or packing material so that the contents will not
move during shipping. For shipping in colder climates, the addition
of temperature control packaging (e.g. Saf-T-Pak Phase Control
Material) can stabilize the culture temperature during transit.
DO NOT FREEZE. Please ship on Mondays, Tuesdays, or
Wednesdays. Recommend early AM overnight shipping or equivalent if
not on courier service.
Sample Processing:
Pink top tubes are sent as whole blood, no processing necessary.
T25 flasks of cells are completely filled with culture medium, closed with non-vented caps, and sealed by wrapping parafilm around cap and neck of flask.

Sample Storage:
Refrigerate the whole blood if it is necessary to be held overnight.
Holding samples over weekends or holidays is not acceptable. DO NOT
FREEZE.
Transport Instructions:
Ship at refrigerated temperature.
