15%MeOH, I guess I have worked with CBP, a 250k protein I used iBlot dry transfer, nitrocellular membrane But the trick is: 1, soak the gel in buffer for 10min before transfer 2, expand the transfer time to 10min (not 7 min) the bands were very sharp and dark semi-dry transfer did not work good

传统方法,1 X transfer buffer: 30mM Tris, 240mM Glycine, 20% methanol, 另外可加可不加SDS(0.2%)。 我一般40伏过夜,nitrocellulose membrane。 另外,也不一定是western问题,首先还是要确定你的基因/蛋白是不是表达了, 做个瞬转吧,250kD 不太难,我做过这么大蛋白瞬转的,做western也检测到了表达。
