Asu II is a restriction enzyme purified from a special isolated strain (#94S) with a concentration of 10 U/µl. It is an isoschizomer to BstB I. Restriction endonucleases are used in biotechnology for gene cloning, to cut DNA in smaller strands to study similarities and differences in fragment length among individuals like in RFLP (Restriction Fragment Length Polymorphism). BIORONs restriction enzymes show high purity and activity.
Asu II can be heat-inactivated after 20 min at 65°C and shows 100% activity in BIORON buffers M and K (supplied with the enzyme). Please note that activity of Asu II is blocked by CpG methylation.
