Activity
One unit is defined as the amount of enzyme required to digest 1 µg of lambda DNA in 1 hour at 37 °C in 50 µL of assay buffer.
DNA degradation
Incubation of single stranded and double stranded radiolabeled oligonucleotides with 10 units of the enzyme for 4 hours at 37 °C.
Star Acitvity
After 160-fold overdigestion (10 U/µg Lambda DNA for 16 hours at 37 °C) with enzyme the fragmentation pattern is analysed. No detectable changes compared to the theoretical fragmentation pattern are considered as absence of star activity.
Description
DraI is an endonuclease enzyme isolated from strains of Deinococcus radiophilus having the DraI gene, and is part of the restriction modification system. In molecular biology it is used as a restriction enzyme.It recognizes the following sequence and produces a blunt end.
Includes
• DraI - 100 μl
• 10X Reaction Buffer - 1.0ml
