DESCRIPTION
General description
Boric acid is a weak acid and is widely used in multi-purpose solutions (MPS) as a buffering agent.[1] It is less toxic and non-volatile in nature.[2]
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) 
Biochem/physiol Actions
Boric acid has antibacterial and fungicidal properties. It is used in the periodontal therapy as an irrigation solution as it elicits bactericidal effects in microbial biofilms in root canal. Boric acid may favor osteoblastic activity and inhibit bone loss.[2] It inhibits Candida albicans fungal infection and has potential to treat vaginal infection.[3]
