Hi, I'm working with a possible zinc binding protein. Saw your post and was wondering, what is the proper pH range for zinc binding? Thanks, Peter

Hi, are you sure it is your protein precipitating? You will get a cloudy precipitate appearing in HEPES and Phosphate buffers on addition of ZnCl, without protein. cheers charlie >>> dengzq1987 3/31/2010 5:08 pm >>> hello everyone, recently i purify a protein conteining zinc binding domai

hello everyone, recently i purify a protein conteining zinc binding domain,and i want to determine its structure.i get the crystal,but poor diffraction.so i try to adding zinc into the protein to optimize the crystal,but the protein precipitate immidiately even the znic is 1 mM.BTW,we use the
