Biosafety Level:1
Shipped: frozen
Growth Conditions: ATCCmedium 712: PYGTemperature: 25.0°C Duration: axenic Protocol: ATCCNO: 30135 SPEC: This strain is distributed as a frozen stabilate. See general instructions for thawing and storage of frozen material before proceeding. As soon as the shipment arrives, remove the frozen ampule from the dry ice and transfer it directly to a 35C water bath. After thawing the ampule, transfer the contents to a 16 x 125 mm plastic screw-capped test tube containing 5 ml of fresh medium. (Glass test tubes may also be used, but the cultures can be transferred less frequently when maintained in plastic.) Screw the cap on tightly and incubate the tube on a 5-15 degree slant at the appropriate temperature. Subculture every 2-4 weeks by vigorously agitating the culture and aseptically transferring a 0.1 ml aliquot to a fresh tube of medium. Prolongation of the transfer interval can be extended up to 6 months for certain strains of Acanthamoeba, however, this must be determined empirically for each strain.
Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimately responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location.
