Icon Descriptions

Gray property icon for cloned at NEB
The gene encoding this enzyme has been cloned at New England Biolabs, Inc.

Gray property icon for recombinant
This enzyme is purified from a recombinant source.

Gray property icon for engineered for performance
This enzyme has been engineered.

Gray property icon for TimeSaver
This enzyme will digest unit substrate in 5-15 minutes under recommended reaction conditions, and can also be used safely in overnight digestions.

Gray property icon for high fidelity (HiFi)
Indicates that the polymerase is high fidelity.

Gray property icon for Hot Start
Indicates that the polymerase is a hot start/warm start enzyme.

Gray property icon for PCR
This polymerase is used for PCR.

Gray property icon for annealing temperature +3
Ta = Tm + 3°C for the polymerase.

Gray property icon for annealing temperature -5
Ta = Tm – 5°C for the polymerase.

Gray property icon for CutSmart Gray property icon for NEBU Gray property icon for NEB 1.1 Gray property icon for NEB 2.1 Gray property icon for NEB 3.1
Gray property icon for rCutSmart Gray property icon for NEB r1.1 Gray property icon for NEB r2.1 Gray property icon for NEB r3.1
Indicates which reaction buffer is supplied with the enzyme for optimal activity. Enzymes with buffer requirements not met by one of the four standard NEBuffers are supplied with their own unique NEBuffer (NEB U). NEBuffers are color-coded (NEBuffer r1.1 & 1.1 - yellow, NEBuffer r2. & 2.1 - blue, NEBuffer r3.1 & 3.1 - red, rCutSmart & CutSmart - green) and supplied as 10X stocks with each enzyme.

Gray property icon for dilA Gray property icon for dilB Gray property icon for dilC
Indicates which diluent buffer (A, B or C) is recommended for making dilutions of restriction enzymes.

Gray property icon of arrow, representing extraction-free PCR
Indicates the product can amplify DNA directly with no need for extraction.

Gray property icon for incubation temperature 25° Gray property icon for incubation temperature 37°
Indicates the enzyme's optimum incubation temperature.

Gray property icon for multi-site
Indicates that the restriction enzyme requires two or more sites for optimal cleavage. 

Gray property icon for SAM
This enzyme is supplied with a separate tube of S-adenosylmethionine (SAM). To obtain 100% activity SAM should be added to the 1X reaction mix as indicated. When required, a concentrated stock of SAM is supplied with the enzyme.

Gray property icon for BSA
This enzyme is supplied with a separate tube of bovine serum albumin (BSA). To obtain 100% activity BSA should be added to the 1X reaction mix to a final concentration as indicated.

Gray property icon for rAlbumin
This enzyme is supplied with a separate tube of Recombinant Albumin (rAlbumin). To obtain 100% activity rAlbumin should be added to the 1X reaction mix to a final concentration as indicated.

Gray property icon for dam Gray property icon for dcm Gray property icon for CpG
Cleavage with this restriction enzyme may be blocked or impaired when the substrate DNA is methylated by either the dam or dcm or CpG methylase.

Gray property icon for heat inactivation yes Gray property icon for heat inactivation no Gray property icon for heat inactivation 65° Gray property icon for heat inactivation 80°
Indicates whether or not the enzyme can be heat inactivated. Enzymes are first tested by incubation at 65°C for 20 minutes; any enzyme not inactivated at 65°C is then tested by incubation at 80°C for 20 minutes.

Gray property icon for blue white certified
This enzyme has passed the blue/white selection assay. This assay is performed on enzymes with single sites in cloning vectors, it is an extremely sensitive measure of the integrity of DNA fragment ends after excess digestion with the enzyme.
