Recombinant DOT1L Catalytic Domain Enzyme Description: Recombinant human DOT1 protein, catalytic domain (DOT1L, KMT4, accession Q8TEK3, amino acids 1-472), containing an N-terminal GST tag, expressed in E. coli. DOT1 is a histone methyltransferase, catalyzing the methylation of histone H3 at lysine 79 on nucleosomal substrates.

Recombinant DOT1L Catalytic Domain Enzyme Formulation: Recombinant GST-DOT1L (1 µg/µl) 100 mM Tris pH 8.0, 5 mM glutathione and 25% glycerol.

Storage and Stability: Stable for six months at -80°C from date of receipt. For best results, aliquot and avoid multiple freeze/thaws.

Application Notes: Recombinant DOT1L Catalytic Domain, human is useful for histone H3 methylation experiments, enzyme kinetics and inhibitor screening. Use of 3-5 µg DOT1L per reaction with HeLa or recombinant nucleosomes as a substrate is recommended.
