title: Establishment of the origin of a porcine cell line by chromosome banding techniques and scanning.
abstract: Use of cultured cells in diagnostic virology implies the necessity to establish the genetic origin of the cells. Chromosome analysis, performed on a cell line of pig embryo kidney cells (PEK), made the porcine origin of the cells plausible. Definite proof, however, was furnished by chromosome banding and scanning. A comparison was made between PEK-cells and normal pig chromosomes. One of the chromosomes No. 1 had an interstitial deletion, which provided an useful marker for identification purposes.
