| Application: | TE buffer has been used for:• isolate, resuspend, or store DNA and RNA for PCR or qPCR • gel electrophoresis, including Northern and Southern blotting • bacterial cells, for AmpC disk test, to measure β-lactamases released from the cells • antigen retrieval for immunohistochemistry |
| General description: | Tris EDTA buffer is commonly used in molecular biology for reconstitution and storage of many precipitated biomolecules, including DNA and RNA. Tris-HCl is a commonly used buffer and EDTA is a metal chelating agent. TE buffer solubilizes nucleic acids while protecting the molecules from degradation. It is used in nucleic acid isolation, which may be done prior to nucleic acid gel electrophoresis and Northern or Southern blot hybridization. |
