Description | 1. Tris and Tris Hydrochloride have been useful as buffers in a wide variety of biological system. Both of these need to be mixed together to provide a buffer with pH between 7 and 9 to provide adequate buffering. 2. Uses include pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications. |
