WebThe common temperature for inactivation is 95°C. Even in the typical mouse-tail protocol, proteinase K is regularly used to inhibit harmful nucleases. And the addition of proteinase K occurs during the digestion step. The use of EDTA is also suggested to help the inactivation of nucleases by inhibiting Mg 2+ dependent nucleases. WebA restriction enzyme is a DNA-cutting enzyme that recognizes specific sites in DNA. Many restriction enzymes make staggered cuts at or near their recognition sites, producing ends with a single-stranded overhang. If two DNA molecules have matching ends, they can be joined by the enzyme DNA ligase.

WebIn my experience TE buffer is perfect for all molecularbiology applications (cloning, digestion, amplification, PCR, etc.). The EDTA will of course complex bivalent cations, but since the concentration in the buffer is only 1mM and the DNA solution is usually diluted further in PCR or digests, this plays no role in real life applications.
