To study the differences in gene between acute focal ischemia and non ischemia tissues in rat so as to clone the related gene of brain ischemia. The fluorescence differential display was applied to screen the differential expression gene between focal brain ischemia and non ischemia region. After identification by reverse Northern blot and RT PCR, the full length of the target EST R6 that was not highly homologous with the known gene was cloned by 5′RACE. R6 in 4 821 bp full length was successfully cloned ...
