Strain Designations 2HH
Biosafety Level 2
Isolation
clinical specimen - human
Vienna Austria
Isolation date: 1996
Product Format frozen
Storage Conditions liquid nitrogen vapor phase
Type Strain no
Medium Medium 712: PYG w/ Additives
Growth Conditions
Temperature: 25.0°C
Duration: axenic
Protocol: 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.
Interval: every month
