Characterization of invertebrate cell lines. IV. Isozyme analyses of dipteran and acarine cell lines.

Cell extracts of five mosquito cell lines and a tick cell line were examined for four cellular isozymes using a cellulose-acetate electrophoretic technique. This method distinguished the cell lines that were derived from the different species. Intraspecies distinctions were not made using the cell lines tested; the significance of this finding is discussed. The usefulness of this technique in identifying a potentially mislabeled cell line was demonstrated.
