Description

Application

Buffer component in a SDS-gradient gel electrophoresis system that separates polypeptides in the molecular weight range of 1500 to 100,000. Used as a spacer in isotachophoresis of proteins. Also used as a buffer for the determination of alkaline phosphatase activity.

2-Amino-2-methyl-1,3-propanediol can be used to study biological buffers. 2-Amino-2-methyl-1,3-propanediol has been used in a study to afford a new family of isostructural octanuclear Cu4Ln4 complexes. 2-Amino-2-methyl-1,3-propanediol has also been used in a study to improve cooling refrigerants for low-temperature applications.
