清洗预膜一体剂? 各位高人有谁用过清洗预膜一体剂的,也就是说,清洗完不用换水,在高浊度,高铁环境下就能预膜的 预膜剂 ? 个人觉得如果换水后再预膜的话,刚洗完的设备在换水那段时间又会很快产生浮锈(因为一般厂家换水速度都很慢),即使加了 钝化剂 ,预膜应该是要求洁净的金属表面的吧。 有谁清洗时,从一开始挂的旧挂片上最后也能产生漂亮的膜的,而不是只在预膜时挂入新挂片,请指教?查看更多 5个回答 . 2人已关注

Lys侧链氨基的修饰方法? 最近要做一个长肽,要在固相上对Lys的侧链进行修饰,我选择的方法是先把Fmoc-Lys(X)-OH做成Fmoc-Lys(X)-HMP-AM 树脂 之后再脱除X。 起初我选择的是Fmoc-Lys(Mtt)-OH,而且效果也不错,但由于目前国内能够做出合格的Fmoc-Lys(Mtt)-OH的厂家不多,于是不得不更换 赖氨酸 的保护基。 我想问一下如果我先合成出Fmoc-Lys(Boc)-HMP-AM树脂,再在0度下用20%TFA/DCM脱除Boc过程中会不会使Lys与HMP-AM树脂之间的酯键断裂,有没有人做过这方面的工作啊? 急需高人指点,不胜感激!!查看更多 6个回答 . 1人已关注
