Recombinant JMJD1B / KDM3B protein gel. JMJD1B / KDM3B protein was run on an SDS-PAGE gel and stained with Coomassie blue.
JMJD1B / KDM3B activity assay. Recombinant JMJD1B / KDM3B activity measured using a demethylation assay. MALDI-TOF was used for detection.
Recombinant JMJD1B / KDM3B protein activity assay. 3. 3 μM H3K9me2 peptide was incubated with recombinant JMJD1B / KDM3B protein in reaction buffer for 1 hours at room temperature. JMJD1B / KDM3B enzyme was used in a HTRF assay to determine enzyme linearity. Demethylated peptide (H3K9me0) was measured using H3K9me0-specific antibody.
