Pst I is a restriction enzyme purified from E. coli strain that carries the cloned Pst I gene from Providencia stuartii. It has a concentration of 10 U/µl. 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.
Pst I can be heat-inactivated with 20 min at 80 °C and shows 100% activity in BIORON buffers H and K (supplied with the enzyme).
