| Isolation： | blood of pike, Esox lucius, Czech Republic |
| Product Format： | frozen |
| Type Strain： | no |
| Comments： | blood parasite of fish |
| Medium： | ATCC® Medium 2213: Biphasic trypanoplasma medium (SNB-9) |
| Growth Conditions： | Temperature: 20.0°C Duration: axenic |
| Cryopreservation： | 1.xa0xa0 Harvest cells from several cultures in the late logarithmic or early stationary phase of growth.xa0 Vigorously agitate by inverting several times to suspend the cells.xa0 Maintain cells on ice between manipulations. 2.xa0xa0 Aseptically transfer the cell suspension to 15 ml plastic centrifuge tubes. 3.xa0xa0 Centrifuge at ~800 x g for 5 min. 4.xa0xa0 While cells are centrifuging, prepare a 10% solution of DMSO in liquid overlay from ATCC medium 2213.xa0 Cool on ice. 5.xa0xa0 Remove the supernatant and pool the cell pellets to the final volume desired with fresh medium overlay. 6.xa0xa0 Combine the cell suspension with an equal volume of 10% DMSO cryoprotectant solution (prepared in step 4) to yield a final concentration of 5% DMSO. 7.xa0xa0 Dispense in 0.5 ml aliquots to 1.0-2.0 ml Nunc vials (special plastic vials for cryopreservation). 8.xa0xa0 Place the vials in a controlled rate freezing unit.xa0 From room temperature cool at -1°C/min to -40°C.xa0 At -40°C, plunge ampules into liquid nitrogen.xa0 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. (The cooling rate in this apparatus is approximately -1°C/min.). xa0 9.xa0xa0 Store ampules in a liquid nitrogen refrigerator until needed. 10.xa0xa0xa0xa0xa0xa0xa0xa0xa0 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.xa0 Allow the ampule to thaw completely (2-3 min). 11.xa0xa0xa0xa0xa0xa0xa0xa0xa0 Immediately after thawing, aseptically remove the contents and transfer to a fresh test tube of ATCC Medium 2213. 12.Screw the cap on tightly and incubate at 15-20°C on a 15° horizontal slant.xa0 Observe the culture daily and transfer when numerous trophozoites are observed.xa0xa0xa0xa0xa0xa0xa0xa0xa0 |
