Actinophrys sol Ehrenberg
Actinophrys sol Ehrenberg
规格:
货期:
编号:TS176114
品牌:Testobio
产品名称： Actinophrys sol Ehrenberg
商品货号： TS176114
Biosafety Level： 1

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： Brackish pond water, Shukkei-en Garden, Hiroshima, Japan, 1994
Product Format： frozen
Storage Conditions： Frozen Cultures:
-70°C for 1 week; liquid N2 vapor for long term storage

Freeze-dried Cultures:
2-8°C

Live Cultures:
See Protocols section for handling information
Type Strain： no
Medium： ATCC® Medium 2454: Actinophrys medium
Growth Conditions：
Temperature: 20°C to 25°C
Cryopreservation： Reagents
Cryoprotective Solution
DMSO 1.0 mL
Betaine 1.0 mL
Fresh growth medium 8.0 mL

Harvest and Preservation

  1. Mix the components in the order listed. When the medium is added to the DMSO the solution will warm up due to chemical heat.
  2. Harvest Actinophrys cells from a culture that has recently passed peak density by centrifugation at 300-400 x g for 5 min.
  3. Adjust the concentration of cells to 1-2 x 104/mL in fresh medium.
  4. Mix the cell preparation and the cryoprotective solution in equal portions by adding the cryoprotective solution to the cell suspension in 2 equal aliquots approximately 1 min apart.
  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 vials in a controlled rate freezing unit. From room temperature cool at -1°C/min to -40°C. If freezing unit can compensate for the heat of fusion, maintain rate at -1°C/min through heat of fusion. At -40°C plunge ampules 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. Ampules are stored in either the vapor or liquid phase of a nitrogen refrigerator.
  8. To establish a culture from the frozen state place the vial in a 35°C water bath. Immerse the vial to a level just above the surface of the frozen material. Do not agitate the vial. Immediately after thawing, do not leave in water bath, aseptically remove the contents of the ampule and transfer to a petri plate or T-25 tissue culture flask optionally containing a bed of non-nutrient agar (ATCC medium 919) and 10 mL ATCC medium 2454
  9. Aseptically transfer an appropriate volume of washed Chlorogonium to the petri plate or T-25 flask (see section on MAINTENANCE OF CULTURE).xa0 Incubate the culture at 20-25°C. Once the culture is established, follow the protocol for maintenance of culture.
