PtK1 Cells

PtK1 is a kidney epithelial cell line derived from the rat kangaroo, Potorous tridactylus. Known for its large, flat cells, PtK1 is widely used in microscopy, particularly in studies involving mitosis and chromosome behavior. The large size of its chromosomes makes PtK1 an ideal model for visualizing chromosome dynamics during cell division, making it a popular choice in cytogenetic and molecular biology research. PtK1 cells have also been utilized in studies involving cell fusion and hybridization, particularly between marsupial and eutherian species. These cells are often employed in somatic cell genetics due to their suitability for drug resistance selection. Researchers have developed drug-resistant variants of PtK1, making them useful for isolating hybrid cells and advancing our understanding of chromosome segregation and gene mapping in interspecies hybrids.The cells are positive for keratin by immunoperoxidase staining.
