Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Isolation：
laboratory
Product Format： frozen
Storage Conditions： Frozen: -70°C or colder for 1 week, vapor phase of liquid nitrogen for long-term storage
Axenic/Xenic： Axenic
Type Strain： no
Comments：
The host, the free-living platyhelminth Macrostomum lignano, was collected from the Northern Adriatic Sea near Lignano, Italy.
Medium： ATCC® Medium 2673: Thraustochytrid medium
ATCC® Medium 790: By+ medium
Growth Conditions：
Temperature: 25°C
Cryopreservation：
  1. To achieve the best results set up cultures with several different inocula (e.g. 0.25 ml, 0.5 ml, 1.0 ml).xa0 Harvest cultures and pool when the culture that received the lowest inoculum is at or near peak density.
  2. If the cell concentration exceeds the required level do not centrifuge, but adjust the concentration to between 2 x 106 and 2 x 107cells/ml with fresh medium.xa0 If the concentration is too low, centrifuge at 600 x g for 5 min and resuspend the pellet in the volume of fresh medium required to yield the desired concentration.
  3. While cells are centrifuging prepare a 20% (v/v) solution of sterile DMSO as follows:xa0 Add the required volume of DMSO to a glass screw-capped test tube and place it in an ice bath.xa0 Allow the DMSO to solidify.xa0 Add the required volume of refrigerated medium.xa0 Dissolve the DMSO by inverting the tube several times. *NOTE: If the DMSO solution is not prepared on ice, an exothermic reaction will occur that may precipitate certain components of the medium.
  4. Mix the cell preparation and the DMSO in equal portions. Thus, the final concentration will be between 106 and 107 cells/ml and 10% (v/v) DMSO. The time from the mixing of the cell preparation and DMSO stock solution to the start of the freezing process should be no less than 15 min and no longer than 30 min.
  5. Dispense in 0.5 ml aliquots into 1.0 - 2.0 ml sterile plastic screw-capped cryules (special plastic vials for cryopreservation).
  6. Place the vials in a controlled rate freezing unit.xa0 From room temperature cool at -1°C/min to -40°C.xa0 If the freezing unit can compensate for the heat of fusion, maintain rate atxa0xa0xa0xa0xa0xa0xa0 -1°C/min through the heat of fusion.xa0 At -40°C plunge into liquid nitrogen. Alternatively, place the vials in a Nalgene 1°C freezing apparatus.xa0 Place the apparatus at -80°C for 1.5 to 2 hours and then plunge ampules into liquid nitrogen.xa0 (The cooling rate in this apparatus is approximately -1°C/min.)xa0xa0
  7. The frozen preparations are stored in either the vapor or liquid phase of a nitrogen freezer.
  8. To establish a culture from the frozen state place an ampule in a water bath set at 35°C (2-3 min). Immerse the vial just sufficient to cover the frozen material. Do not agitate the vial.
  9. Immediately after thawing, aseptically remove the contents of the ampule and inoculate into 5 ml of fresh ATCC medium 2673 in a T-25 tissue culture flask or 16 x 125 mm screw-capped test tube.xa0 Incubate at 25°C.
