Intact Genomics (IG) PEmax enzyme is the purified recombinant Streptococcus pyogenes Cas9 nickase mutant (H840A)-Murine Moloney Leukemia Virus-Reverse Transcriptase (MMLV-RT) fusion protein3-4 containing a nuclear localization signal (NLS) at the C-terminal for targeting to the nucleus. This enzyme is designed to perform CRISPR prime-editing3-4. The physical purity of this enzyme is ≥85% as assessed by SDS-PAGE with Coomassie blue staining.Product Includes: PEmax enzyme 5x PEmax Nicking Buffer: 20 mM HEPES, 100 mM NaCl, 5 mM MgCl2, 0.1 mM EDTA, pH 6.5 @ 25 °CStore all components at -20°C.
