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.
Physical form
In 50 mM Tris-HCl, pH 7.6.

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
