Phosphatase treatment of linearized vector
Notes
This enzyme is preferable to either Calf Intestinal Phosphatase or Shrimp Alkaline Phosphatase because it is more easily heat-inactivated. After phosphatase treatment of a vector, any remaining activity would remove 5' phosphates from the insert in a subsequent ligation reaction, preventing a successful reaction. Thus, it is critical that the phosphatase be inactivated, purified away, or digested with Proteinase K.
