Prototheca zopfii Kruger
Prototheca zopfii Kruger
规格:
货期:
编号:TS151506
品牌:Testobio
产品名称： Prototheca zopfii Kruger
商品货号： TS151506
Strain Designations： PR-30 UTEX 1438
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：
slime flux of locust tree, Peoria, IL, (?)
Product Format： freeze-dried
Storage Conditions： Freeze-dried: 2°C to 8°C
Axenic/Xenic： Axenic
Type Strain： no
Medium： ATCC® Medium 28: Emmons modification of Sabourauds agar
Growth Conditions：
Temperature: 20-25°C
Cryopreservation：
  1. Harvest cells from a culture which is at or near peak density by adding 3.0 ml fresh ATCC medium 28 broth to the slant and washing cells into suspension.
  2. Adjust the concentration of cells to 4 x 106/ml with fresh broth medium, then dilute to half this concentration by adding an equal amount of a 20% (v/v) sterile DMSO solution in fresh ATCC medium 28 broth.
  3. Dispense in 0.5 ml aliquots into 1.0 - 2.0 ml sterile plastic screw-capped cryules (special plastic vials for cryopreservation).xa0 The time from mixing of the cell preparation and the methanol solution, before the cooling cycle begins, should be no greater than 15 min.
  4. 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
  5. The frozen preparations should be stored in either the vapor or liquid phase of a nitrogen refrigerator. Frozen preparations stored below -130°C are stabile indefinitely. Those stored at temperatures above -130°C are progressively less stabile as the storage temperature is elevated. Vials can be stored between -80 and -70°C for no longer than one week.
  6. To establish a culture from the frozen state place an ampule in a water bath set at 35°C. Immerse the vial to a level just above the surface of the frozen material. Do not agitate the vial.
  7. Immediately after thawing, do not leave in the water bath, aseptically remove the contents of the ampule and add to a fresh slant of ATCC medium 28 or the surface of an agar plate of ATCC medium 28.
  8. Maintain as described above.xa0
