Tool Details

  • Tool name: Pr8/22 Cell Line
  • Tool type: Cell Lines
  • Tool sub-type: Continuous
  • Parental cell line: P388
  • Organism: Mouse
  • Tissue: Lymphatic Tissue
  • Cancer type: Drug resistant
  • Disease: Cancer
  • Growth properties: Suspension
  • Model: Tumour line
  • Conditional: No
  • Description: The cell line Pr8/22 has been derived from P388, a methylcholanthrene-induced lymphoid neoplasm originating in DBA/2 mouse and converted to ascitic form in the first mouse transfer. Pr8/22 is resistant to daunorubicin and is multi drug resistant (MDR). Cells should be treated with the drug at least once a month and before freezing, however after resuscitating daunorubicin should not be added until the first passage. It is advisable to keep a backup culture which is not drug-challenged.
