The total RNA from brain tissue of substantia nigra of PD rats is extracted at the 1st, 2nd, 4th and 8th week and comparison is made between it and that from normal rats. The total RNA, after RNA formaldehyde degenerated sepharose electrophoresis and separation and Northern transfer, is adsorbed unto colloxylin membrane. Then ECL labeled Selenoprotein P and an unknown gene fragment are used as probes to hybridize with the RNA on the colloxylin membrane. And the hybridized result is obtained with enzyme-linked immunosorbent assay. Finally, analysis of OD is made using ONE-Dscan software.
