Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme required to digest 1 µg of λ DNA in 1 hour at 50°C in a total reaction volume of 50 µl.

Reaction Conditions

1X NEBuffer™ r3.1
Incubate at 50°C

1X NEBuffer™ r3.1
100 mM NaCl
50 mM Tris-HCl
10 mM MgCl2
100 µg/ml Recombinant Albumin
(pH 7.9 @ 25°C)

Activity in NEBuffers

NEBuffer™ r1.1: 100%
NEBuffer™ r2.1: 100%
NEBuffer™ r3.1: 100%
rCutSmart™ Buffer: 100%

Diluent Compatibility

Storage Buffer

10 mM Tris-HCl
100 mM KCl
1 mM DTT
0.1 mM EDTA
200 µg/ml Recombinant Albumin
50% Glycerol
pH 7.4 @ 25°C

Heat Inactivation

80°C for 20 minutes

Methylation Sensitivity

dam methylation: Not Sensitive
dcm methylation: Not Sensitive
CpG Methylation: Not Sensitive

Activity at Temperature

@37°C: 50%

Product Notes

  1. Based on the stability of the enzyme in the reaction, incubations longer than 1 hr will not result in improved digestion, unless additional enzyme is added. Please refer to Restriction endonuclease survival in a reaction for more information regarding this topic.
  2. Star activity may result in a low salt buffer, such as rCutSmart Buffer. For an optimal restriction digest protocol please see NEBCloner.
  3. Not sensitive to CpG, dcm, or dam methylation.
  4. Now available as a GMP-grade reagent.
  5. High Fidelity (HF®) version available (NEB #R3712) supplied with rCutSmart™ Buffer; 37°C incubation temperature.
  6. star activity may result from a glycerol concentration of >5%

FAQs & Troubleshooting

FAQs

  1. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  2. Is this enzyme sensitive to dam, dcm or mammalian CpG methylation?
  3. Does NEB offer any BSA-free and/or animal origin-free restriction enzymes for linearization of plasmids for mRNA vaccine development?
  4. Can you tell me more about the switch from BSA to Recombinant Albumin (rAlbumin) in NEBuffers?
