  • NEB supplies a variety of phosphatases for use in cloning, such as preparation of templates for 5´end labeling, prevention of recircularization of cloning vectors, enhancing yields of RNA in transcription reactions.

    Phosphatases catalyze the removal of 5´ phosphate groups from DNA and RNA (Shrimp Alkaline Phosphatase (NEB #M0371) and Antarctic Phosphatase (NEB #M0289). Inorganic phosphatases catalyze the hydrolysis of inorganic pyrophosphate to form orthophosphate (Pyrophosphatase, Inorganic (yeast) (NEB #M2403) and Thermostable Inorganic Pyrophosphatase (NEB #M0296)).

    ATP Sulfurylase (NEB #M0394) catalyzes the activation of sulfate by transferring sulfate to the adenine monophosphate moiety of ATP to form adenosine 5´-phosphosulfate (APS) and pyrophosphate.
