Figure 7From: Properties of cellular and serum forms of thymidine kinase 1 (TK1) in dogs with acute lymphocytic leukemia (ALL) and canine mammary tumors (CMTs): implications for TK1 as a proliferation biomarkerSerum from a healthy dog (No. 5) analyzed by Superose 12 column chromatography. (A) Serum thymidine kinase 1 (sTK1) activity in the fractions from the healthy dog (•). (B) Western blot analyses of sTK1 protein in the same fractions. Arrows indicate the elution position of the molecular weight (MW) markers. Numbers represent the fast protein liquid chromatography (FPLC) fractions.Back to article page
