Storage: −20°C
UNSPSC Code: 12352200
Components: Enzyme Solution; SuRE/Cut Buffer H 10x concentrated
RIDADR: NONH for all modes of transport
Analysis Note:
Activity in PCR buffer: <5%
Relative activity in PCR mix (Taq DNA Polymerase buffer) is less than 5%. The PCR mix contained λDNA, primers, 10 mM Tris-HCl (pH 8.3, 20 °C), 50 mM KCl, 1.5 mM MgCl2, 200 μM dNTPs, 2.5 U Taq DNA polymerase. The mix was subjected to 25 amplification cycles.
Other Notes:
For life science research only. Not for use in diagnostic procedures.
Quality:
Absence of nonspecific endonuclease activities
1μg λDNA is incubated for 16hours in 50μl SuRE/Cut Buffer H with an excess of Pvu I. The number of enzyme units which do not change the enzyme-specific pattern is stated in the certificate of analysis.
Absence of exonuclease activity
Approximately 5μg [3H] labeled calf thymus DNA are incubated with 3μl Pvu I for 4hours at +37°C in a total volume of 100μl 50mM Tris-HCl, 10mM MgCl2, 1mM Dithioerythritol, pH approximately 7.5. Under these conditions, no release of radioactivity is detectable, as stated in the certificate of analysis.

Specificity:
Pvu I recognizes the sequence CG°AT↓ *CG and generates fragments with 3′-cohesive termini.
Recognition sites: CG°AT*CG
CG°AT*CG
Restriction site: CG°AT↓*CG
