Abstract

A composition containing a nuclease, preferably Exonuclease I, and a phosphatase, preferably Shrimp Alkaline Phosphatase, wherein the enzymes are combined in a single composition yet each enzyme retains significant functional activity over time. Combining Exonuclease I and Shrimp Alkaline Phosphatase into one composition allows simplified processing of amplified DNA to degrade residual primers and nucleotide triphosphates thereby facilitating subsequent DNA analysis.
