      gel filtration  

       

      1.     p43,p38,wild type MEF cell 100π dish 20장에 culture(37 CO2 5%).

      2.     TE처리후 cold 1XPBS spindown 하고, 다시 한번 cold 1XPBS washing한다.

      3.     hypotonic solution(10mM HEPES pH7.6, 10mM KCL, 1.5mMMgCl2, 0.5mM EGTA, 10mM NaF, 1mM PMSF, Protease  inhibitor cocktail<Roche> ) syringe(needle size 23G) lysis 시킴.

      4.     4, 14000 rpm에서 15min centrifuge.

      5.     동일 volume solution(10mM HEPES pH7.6, 150mM KCL, 1.5mMMgCl2, 0.5mM EGTA, 10mM NaF, 1mM PMSF, Protease  inhibitor cocktail<Roche> )을 첨가해서 80mm KCl solution으로 만든다.

      6.     9mg/ml vivaspin(VIVASCIENCE)을 이용하여 농축 시킨다. 0.22um filter filtering을 한 후 단백질 농도를 잰다.

      7.     (10mM HEPES pH7.6, 80mM KCL, 1.5mMMgCl2, 0.5mM EGTA, 10mM NaF, 1mM PMSF, Protease  inhibitor cocktail<Roche> ) buffer FPLC pump column(Pharmacia, Sephacryl S-300 High resolution, separate range 10Kda-1500KDa ) equilibrium 시킨다.

      8.     sample 500ul(4mg/500ul) injection flow rate 1.0ml/min, fraction size 1ml gel filtration program 4돌린다.

      9.     일부 fraction을 취해서 western blotting을 한다.
