Female Rat Kangaroo Kidney Epithelial Cells (PtK1)

The PtK1 cell line was derived in 1962 from the kidney of a normal adult female Potorous tridactylus, a species of rat kangaroo prevalent in Australia. The epithelial line is believed to be the first permanent cell line of marsupial origin to be established. PtK1 cells are positive for keratin by immunoperoxidase and fluorescence staining and are susceptible to vesicular stomatitis (Indiana strain).
