Beschreibung

Application

Ammonium tartrate dibasic can be used to study biochemicals and reagents, biological buffers, chelators, protein structural analysis, proteomics and X-ray crystallography. Ammonium tartrate dibasic has been used in a study to research the crystal optimization and preliminary diffraction data analysis of the Smad1 MH1 domain bound to a palindromic SBE DNA element.
