Preparationoftubulin
Although many protocols for tubulin preparation are available, the procedure described below is the simplest and highest yielding preparation I have done. The protocol calls for 3 pig brains, and should yield ~ 60 mg of purified tubulin. Solutions and reagents: 100g P-11 cellulose phosphate fibrous cation exchanger (Whatman Inc, Clifton NJ) 6L 0.1M HCl 6L 0.1 M NaOH 2L 0.1 M MgSO4 2L 10x C......阅读全文
