General description
Recombinant, human purine nucleotide phosphorylase expressed in E. coli without tags. Purine nucleoside phosphorylase catalyzes the phosphorlysis of N-ribosidic bonds of purine nucleosides and deoxynucleosides in a reversible reaction. Human PNP is a target for therapeutic T-cell immune response intervention. Useful in the detection of inorganic phosphate from biochemical reactions.

Recent efforts in biological engineering have made detection of nucleic acids in samples more rapid, inexpensive and sensitive using CRISPR-based approaches. We expand one of these Cas13a-based methods to detect small molecules in a one-batch assay. Using SHERLOCK-based profiling of
