描述信息
Other Notes
Running buffer component with methylmercuric hydroxide gels1; Buffer component in DNA digest analysis with capillary electrophoresis2
Application
Boric acid can be used to study molecular biology, DNA and RNA purification, biological buffers and molecular biology reagents. Boric acid has been used to test the toxic effects of boron on growth and antioxidant system parameters of maize (Zea mays L.) roots. Boric acid has also been used to study the effect of time period after boric acid injection on (10)B absorption in different regions of adult male rat′s brain.
