10 mM Mes ( 2-(N-Morpholino)ethanesulfonic acid hydrate or 4-Morpholineethanesulfonic acid) buffer In each of the buffers I mention above which is the weak acid and the conjugate base? MES is often known as one of the original Good's buffers. The following are recipes for a number of common biological buffers taken from Ruzin, 1999 Plant Microtechnique and Microscopy.When choosing one for a particular application select a buffer based on its pH optimum and biological properties rather than its historical use. MES is a zwitterionic N-substituted aminosulfonic acid known as a Good’s buffer, active in the pH range 6-8 with a pKa of 6.10 at 25°C. MES it is not absorbed through cell membranes, and it is essentially transparent to UV light. View Recipes for stock solutions and general use buffers How to determine volumes to use to obtain a certain concentration: • C 1V 1 = C 2V 2 where C = concentration and V = volume • Make sure to match units! BES-buffered saline is often used in the calcium phosphate-mediated transformation of mammalian cells. MES, also referred to as 4-Morpholineethanesulfonic acid, is a zwitterionic buffer primarily used as a running buffer for resolving very small proteins on bis-tris gels. No. 2. Recipe can be automatically scaled by entering desired final volume. You want 75 mL at 150 µg/mL. • Example: You have a stock solution at 100 mg/mL.
