Applications and Usages
1, buffer, only nucleic acids and proteins are widely used as solvents.
2, It is used for protein crystal growth under different pH conditions.
3, buffer having a low ionic strength can be used nematode (C. elegans) is formed lamin (lamin) intermediate fibers.
4, It is a major component of protein electrophoresis buffer.
5, It for the preparation of a surfactant, a vulcanization accelerator, and some drug intermediates.
6, It titrated also used as standard.
