Recombinant PRDM9 protein was expressed in E.coli and is supplied in 20 mM Tris pH 7.5, 300 mM NaCl, 0.5 mM TCEP, 5 % glycerol, 1 μM ZnCl2. Please refer to product insert upon arrival for lot-specific concentration.


PRDM9 (PR Domain Containing 9) is a Histone methyltransferase that specifically trimethylates Lys-4 of histone H3 during meiotic prophase and is essential for proper meiotic progression. PRDM9 has the ability to mono- and dimethylate Lys-4 of histone H3. H3 Lys-4 methylation represents a specific tag for epigenetic transcriptional activation. Plays a central role in the transcriptional activation of genes during early meiotic prophase (By similarity).

Application Notes

Recombinant PRDM9 is suitable for use in enzyme kinetics, inhibitor screening, and selectivity profiling.

HMT Assay Conditions: 50 mM TrisCl, pH 8.5, 30 mM NaCl, 5% glycerol, 2 mM DTT, 5, 25, and 50 μM H3 (1-24) peptide, 100 nM Recombinant PRMT5 protein at room temperature.
