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.

Nucleic acids research, 48(17), e101-e101 (2020-08-17)
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
