Frequently asked questions
What is the difference between TE pH 7.4 and TE pH 8.0?
Both contain 10 mM Tris-HCl and 1 mM EDTA. TE pH 8.0 (BZ210) is the most common choice for DNA storage; TE pH 7.4 is used when a protocol specifies a near-neutral pH.
What is the composition of BZ230?
10 mM Tris-HCl and 1 mM EDTA, adjusted to pH 7.4, in high-purity water.
Can DNA in TE go straight into PCR or enzyme reactions?
Yes, in small volumes. EDTA chelates magnesium, so for large additions use EDTA-free 10 mM Tris-HCl (BZ234).
Is BZ230 sterile?
Yes. It is autoclaved and supplied DNase-free. Use aseptic, nuclease-free technique after opening.
How should TE buffer pH 7.4 be stored?
Store at 2–30 °C, tightly closed. Unopened bottles have a 1-year shelf life and ship at room temperature.
