Crithidia mellificae Langridge and McGhee
Crithidia mellificae Langridge and McGhee
规格:
货期:
编号:TS168678
品牌:Testobio
产品名称： Crithidia mellificae Langridge and McGhee
商品货号： TS168678
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：
yellow jacket, Vespula squamosa, Athens, GA, 1978
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：
Riboprinting and taxonomy
Multiple distinct site-specific elements in miniexon arrays
Medium： ATCC® Medium 355: Crithidia medium
Growth Conditions：
Temperature: 25°C
Cryopreservation：
  1. Prepare a 10% (v/v) sterile DMSO solution in fresh ATCC Medium 355.xa0
  2. Transfer a culture at peak density to centrifuge tubes and centrifuge at 525 x g for 5 minutes.
  3. Remove the supernatant and resuspend the cells in ATCC medium 355 to a concentration of 2 x 106 to 2 x 107 cells/ml.
  4. Mix the cell preparation and the DMSO in equal portions. Thus, the final concentration will be between 106 and 107 cells/ml and 5% (v/v) DMSO.
  5. Distribute the cell suspension 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 the mixing of the cell preparation and DMSO stock solution before the freezing process is begun should be no less than 15 min and no longer than 30 min.
  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 approximatelyxa0xa0xa0xa0xa0xa0xa0xa0xa0xa0xa0xa0 -1°C/min.) xa0
  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 355 in a 16 x 125 mm screw-capped test tube. Incubate upright at 25°C with caps screwed on tightly.
