dodecyl sulfate-polyacrylamide gel electrophoresis (SDSPAGE)
and transferred to polyvinylidene fluoride membranes.
Blots were blocked using non-fat dry milk for 1 hour. After
blocking, membranes were probed with ADK primary
antibody (Santa Cruz, 1/1000). Then anti-rabbit IgG antibody
conjugated with horseradish peroxidase (Santa Cruz, 1/8000)
was used for 1 hour at room temperature. Subsequently, the
blots were reprobed with a ß-actin antibody (1:2000, Abcam,
ab8227, USA). Then, the blots were treated with Electro
Chemi Luminescence reagents (Amersham Biosciences,
UK). For quantification of protein intensities, western blot
bands were visualized on radiograph film and evaluated by
Image J software. Human umbilical cord tissue was used in
accordance with the Declarations of Tehran University of
Medical Science and Stem Cell Research Center Committee
after obtaining written informed consent from the mother.
