规格:
货期:
编号:TS134560
品牌:Testobio
产品名称： Nosema trichoplusiae Tanabe and Tamashiro
商品货号： TS134560
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：
Trichoplusia ni, Columbia, MO, 1977
Product Format： frozen
Storage Conditions： Frozen: -70°C or colder for 1 week, vapor phase of liquid nitrogen for long-term storage
Type Strain： no
Cryopreservation：
  1. Harvest parasite spores according to the protocol for maintenance in vivo.
  2. Centrifuge at 1400 x g for 10 min.
  3. While spores are centrifuging prepare a 75% (v/v) solution of sterile glycerol in fresh Hanks Balanced Salt Solution xa0(HBSS) (ATCC cat. 30-2101) or sterile distilled water.
  4. Pool the pellets and adjust the concentration to 2.0 - 4.0 x 109 spores/ml with fresh HBSS or sterile distilled water.
    NOTE:xa0 If the concentration is too low centrifuge at 1400 x g for 10 min and resuspend in the volume of HBSS required to yield the desired concentration.
  5. Mix the cell preparation and glycerol solution in a 1:3 ratio.xa0 The final concentration will be 1.0 - 2.0 x 109 spores/ml and 50% glycerol.xa0 The time from the mixing of the cell preparation and cryoprotective solution to the start of the freezing process should be no less than 15 min. and no more than 30 min.
  6. Dispense in 0.5 ml aliquots to 1.0-2.0 ml sterile plastic screw-capped cryules (special plastic vials for cryopreservation).
  7. 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.)xa0
  8. Store in either the vapor or liquid phase of a nitrogen refrigerator.
  9. To thaw a frozen ampule, place it in a 35°C water bath such that the lip of the ampule remains above the water line. Thawing time is approximately 2 to 3 minutes.xa0 Do not agitate the ampule.xa0 Do not leave ampule in water bath after thawed.
  10. When completely thawed, infect lepidopteran larvae either by placing spores on the surface of their food plant or artificial diet, or by force-feeding with a syringe mounted on a micro-applicator.xa0 Follow the protocol for maintenance in vivo.
