Invitrogen conventional restriction enzymes come with Universal Buffers L, M, H, K, or T (+BSA). Full details for the this restriction enzymes characteristics are included in the tables below.

Consider upgrading to the Invitrogen™ Anza™ restriction enzyme cloning system for superior convenience. Anza restriction enzymes utilize a single buffer and protocol—complete digestion in 15 minutes at 37°C for all types of DNA substrates. Click here for the Anza equivalent restriction enzyme.
Concentration10 U/ µL
ContentsNot I 10X Buffer H (1mL) 10X Loading Buffer (1mL)
Reaction Temperature37°C
Reaction Mixture Not I 1 µL 10X Buffer H 2 µL 0.10% BSA 2 µL 0.10% Trion X-100 2 µL Substrate DNA <1 µg Sterile water to 20 µL
Heat inactivationEnzyme is inactivated by heating at 65°C for 20 minutes.
Star ActivityUnrelated site may be under conditions of low ionic strength, high enzyme concentration, glycerol concentration >5%, or pH >8.0.
Effect of DNA MethylationEnzyme activity is affected by CG methylase depending on the sequence of the recognition site or the sequence following the site.
Unit DefinitionOne unit is the amount of enzyme required to completely digest 1 µg of λDNA in 50 µL of the reaction mixture in one hour at 37°C.
