This product is a Saline-Tris-EDTA (STE) buffer that is ready-to-use. It has a pH specification of 7.6 to 8.0, with a lot-specific pH provided on the certificate of analysis (CofA). This buffer is prepared using Tris base, which has a pH of about 11 in water; the pH is then lowered to the 7.6 to 8.0 range by using hydrochloric acid. Since the pKa of Tris is 8.1, one could say that the buffer is 10 mM in Tris, and just a little over 5 mM in HCl.

Application
- Safer DNA extraction from plant tissues using sucrose buffer and glass fiber filter.: The study demonstrates a novel method for DNA extraction from plant tissues using STE buffer solution, ensuring higher safety and efficiency. This approach improves DNA yield and quality, essential for plant genetic research (Takakura et al., 2012).
- In vitro DNA fragmentation of mitochondrial DNA caused by single-stranded breakage related to macroplasmodial senescence of the true slime mold, Physarum polycephalum.: This study employs STE buffer solution to investigate mitochondrial DNA fragmentation in the slime mold Physarum polycephalum, providing valuable insights into cellular aging processes (Abe et al., 2000).
