WOS: 000286480300007Blood-serum proteins of the known subspecies of Apathya cappadocica (Werner, 1902) were studied comparatively by polyacrylamide disc gel electrophoresis. In order to obtain useful biochemical data for classification, differences between the electrophoreograms of the samples included in the morphologically different subspecies were distinguished qualitatively and quantitatively. These comparisons indicated that electrophoretic results supported morphological discrimination of the known subspecies of A. cappadocica.TUBITAK (The Scientific and Technical Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [TBAG-104T017]This work forms part of a Project (Project No. TBAG-104T017) supported by TUBITAK (The Scientific and Technical Research Council of Turkey)
