產(chǎn)品名稱 Perkinsus marinus (Mackin et al.) Levine
商品貨號 B244033
Strain Designations HCedar13 [FL-10]
Biosafety Level 2

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
eastern oyster, Crassostrea virginica, Cedar Keys, FL, 1998
Product Format frozen
Type Strain no
Medium ATCC® Medium 1886: Perkinsus broth medium
Growth Conditions
Temperature: 25.0°C
Duration: axenic
Protocol: ATCCNO: 50439 SPEC: When the frozen ampule arrives, place it directly into a 35C-water bath and transfer its thawed contents to 14 ml of fresh medium in a T-75 tissue culture flask. Maintain by removing 13 ml of cell suspension weekly and replacing with an equal volume of fresh medium. Alternately, aseptically transfer 1.0 ml of a growing culture to 13 ml of fresh medium in a T-75 tissue culture flask. Please note: This strain has wide tolerances to most environmental variables, i.e., temperature range: 15-35C, salinity range: 10-60 parts per thousand; pH range: 6.0-8.5. The distribution of the species worldwide is not known. In order to avert the introduction of this pathogen into non-endemic areas, all culture wastes must be treated as biohazardous and autoclaved prior to disposal. There are no known mechanisms for eradication of this pathogen from the environment.
Subcultivation

Cryopreservation
1.?? Harvest cells from several cultures which are in logarithmic to late stationary phase of growth.? Vigorously agitate to suspend the cells.

2.?? Aseptically transfer the cell suspension to 15 ml plastic centrifuge tubes.

3.?? Centrifuge at 200 x g for 5 min.

4.?? While cells are centrifuging, prepare a 20% solution of DMSO in ATCC Medium 1886.

5.?? Remove the supernatant and pool the cell pellets into a final volume of 4.5 ml.

6.?? Combine the cell suspension with an equal volume of 20% DMSO cryoprotectant solution (prepared in step 4) to yield a final concentration of 10% DMSO.

7.?? Dispense in 0.5 ml aliquots to 1.0-2.0 ml Nunc vials (special plastic vials for cryopreservation).

8.?? Place the vials in a controlled rate freezing unit.? From room temperature cool at -1°C/min to -40°C.? At -40°C, plunge ampules into liquid nitrogen.

9.?? Store ampules in a liquid nitrogen refrigerator until needed.

10.????????? To establish a culture from the frozen state, place a frozen ampule in a 35°C water bath just enough to cover the frozen material.? Allow the ampule to thaw completely (2-3 min).

11.????????? Immediately after thawing, aseptically remove the contents and transfer to a T-25 tissue culture flask containing 10 ml of fresh ATCC medium 1886.

12.Screw the cap on tightly and incubate at 25°C.? Observe the culture daily.? Transfer the culture when many trophozoites are observed.?????????
