WebA large advantage of fluorescent tags is that they are non-toxic and can, therefore, be used in live cells. Despite being large tags, they tend to be minimally disruptive to most proteins 1 . Although GFP, with a molecular weight of 26.9 kDa, is one of the most widely used fluorescent tags, there are several important points to consider. WebTrimethyl phosphate is prepared by treating phosphorus oxychloride with methanol in the presence of an amine base: POCl 3 + 3 CH 3 OH + 3 R 3 N → PO (OCH 3) 3 + 3 R 3 NH + Cl −. It is a tetrahedral molecule that is a weakly polar solvent.
