Purity: > 90% by SDS - PAGE Format: Liquid. 20mM Tris-HCl buffer (pH8.0) containing 20% glycerol, 0.1M NaCl, 1mM DTT . TRDMT1(tRNA aspartic acid methyltransferase 1), also known as DNMT2, specifically methylates cytosine 38 in the anticodon loop of tRNA(Asp). Recombinant human TRDMT1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.
