Neospongiococcum excentricum Deason and Bold
规格:
货期:
编号:TS185204
品牌:Testobio
产品名称： Neospongiococcum excentricum Deason and Bold
商品货号： TS185204
Strain Designations： HS1 B
Application：
Produces carotenoids
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： Division mutant derived from wild type strain UTEX 1232, 1987
Product Format： frozen
Storage Conditions： Frozen: -70°C or colder
Freeze-Dried: 2°C to 8°C
Live Culture: See Protocols Section
Type Strain： no
Disclosure： This material is cited in a US or other Patent and may not be used to infringe the claims. Depending on the wishes of the Depositor, ATCC may be required to inform the Patent Depositor of the party to which the material was furnished. This material may not have been produced or characterized by ATCC.
Comments：
Carotenoid producing culture
Medium： ATCC® Medium 2001: CYU 2%
Growth Conditions：
Temperature: 25°C to 35°C
Cryopreservation：
  1. Harvest cells from a culture that is at or near peak density by centrifugation at 800 x g for 5 min.
  2. Adjust the concentration of cells to 2 x 106 - 2 x 107/mL in fresh medium.
  3. While cells are centrifuging prepare a solution of 14% (v/v) sterile DMSO solution in fresh medium.
  4. Mix the cell preparation and the cryoprotective solution in equal portions. Thus, the final concentration will be 106 - 107 cells/mL and 7% (v/v) DMSO. The time from the mixing of the cell preparation and cryoprotective stock solution to the start of the cooling cycle should be no less than 5 min and no greater than 15 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 atxa0-1°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.) xa0
  7. 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 should not be stored above -55°C.
  8. To establish a culture from the frozen state place an ampule in a water bath set at 35°C. Immerse the vial just to a level just above the surface of the frozen material. Do not agitate the vial.
  9. Immediately after thawing, do not leave in the water bath, aseptically remove the contents of the ampule and add to a centrifuge tube containing 5 mL of ATCC medium 2001.xa0
  10. Incubate the culture at 50-100 µEinsteins/m2/s irradiance at 25-35°C.xa0 Maintain under a 14/10h light-dark photoperiod.
