General description
Boric acid is a weak acid and is widely used in multi-purpose solutions (MPS) as a buffering agent. It is less toxic and non-volatile in nature.
Application
Boric acid has been used as a component of tris borate buffer:
• for native polyacrylamide gel electrophoresis (PAGE) and denaturing urea-PAGE of tRNA samples(80)
• for urea-polyacrylamide electrophoresis of RNA samples(81)
• for agarose gel electrophoresis of DNA samples(82)
