Taq II

Source

Purified from E.coli strain that carries the cloned taqRII gene from Thermus aquaticus

Unit Definition

One unit is the amount of enzyme required to digest 1 µg of pBR322 DNA to obtain stable digestion pattern in 1 hour in a total reaction volume of 20 µl

Reaction Temperature

65°C

Heat Inactivation

No

Reaction Buffer

50 mM Tris-HCl (pH 8.5 at 25°C)
10 mM MgCl₂
1 mM dithiothreitol

Notes:

1. Avoid multiple cycles of freezing/thawing of the stock reaction buffer no more than 3 times
2. Thawing should be performed at temperatures not exceeding 10°C
3. Recommended procedure is to divide the provided reaction buffer into smaller portions and preserve them at -70°C for long-term
4. Temperature of -20°C should be used only for short-term storage
