TE

10X pH 8.0 Recipe

• 100mM Tris-Cl (pH 8.0)
• 10mM EDTA (pH 8.0)

Notes

• Use Tris base and adjust the pH to 8.0 using HCl.
• TE buffer is often used to store DNA. However, you should realize that the EDTA in TE can chelate the Mg²⁺ ions necessary for many reactions such as restriction digests and PCR. So when using DNA that was suspended in TE you should keep track of the amount of EDTA in the mix to make sure there is still enough Mg²⁺ for your reaction to proceed successfully.
