JARID1C (KDM5C) Homogeneous Assay Kit

The JARID1C Homogeneous Assay Kit is designed to measure JARID1C activity for screening and profiling applications. JARID1C, also known as SMCX (Smcy homolog, X-linked), KDM5C, or XE169, is a JumonjiC (JmjC) and ARID domain-containing histone lysine demethylase that exhibits demethylation activity toward H3-K₄Me² and H3-K₄Me³. The JARID1C Homogeneous Assay Kit comes in a convenient AlphaLISA^® format (Scheme 1), with biotinylated histone H3 peptide substrate, primary antibody, demethylase assay buffer, and purified JARID1C for 96 enzyme reactions. The key to the JARID1C Homogeneous Assay Kit is a highly specific antibody that recognizes demethylated substrate. With this kit, only three simple steps on a microtiter plate are required for methyltransferase detection. First, a sample containing JARID1C enzyme is incubated with the biotinylated substrate. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts.

Scheme 1: Our histone demethylase assays utilize highly specific antibodies that recognize demethylated histone substrate. First, a sample containing the enzyme is incubated with a biotinylated substrate. Next, acceptor beads and primary antibody are added, then donor beads, followed by reading the Alpha-counts, as shown above.
