Tricine, ultra pure

Tricine is a commonly used electrophoresis buffer and is also used in resuspension of cell pellets. It has a higher negative charge than glycine allowing it to migrate faster. In addition its high ionic strength causes more ion movement and less protein movement. This allows for low molecular weight proteins to be separated in lower percent acrylamide gels. Tricine has been documented in the separation of proteins in the range of 1 to 100 kDa by electrophoresis.
