Preparationoftubulin2
DAY 2: Cycling preparation of MT protein.Keep the brains in an evacuated plastic ziplock bag buried in ice from the time of slaughter during transport back to the laboratory. In a 4oC cold room, carefully and thoroughly remove the meninges and any blood-red tissue from the surface, stem, and within the folds of each brain. Do this by both picking tissue away by hand and wiping with kimwipes. The dry w......阅读全文
