Complex of human DNA methyl-transferase 3B (DNMT3B), GenBank Accession No. NM_006892, a.a. 564-853(end) with N-terminal His-tag, MW=34 kDa, and DNMT3L (GenBank Accession No. NM_013369), a.a. 160-387(end), with an N-terminal GST-tag, MW = 52 kDa, co-expressed in a baculovirus-infected Sf9 cell expression system.

Q9UBC3 (DNMT3B), Q9UJW3 (DNMT3L)

≥0.52 pmol/min/µg.

Assayed using BPS Bioscience DNMT3B Assay Kit, Cat. #52034. Add 50 µl reaction mix containing DNMT3B/DNMT3L to wells coated with DNMT substrate. Incubate 2 hr at 37°C. Add antibody against 5-methylcytosine, then HRP-labeled secondary antibody followed by chemiluminescent detection.

40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 16 mM glutathione, and 20% glycerol

Aqueous buffer solution

>6 months at –80°C.

Useful for the study of DNA methylation, screening inhibitors, and selectivity profiling.

Avoid freeze/thaw cycles.
