The LanthaScreen® Tb-anti-Histone H3K4me2 antibody is a key component of the BacMam Histone H3K4me2 Cellullar Assay (A14164). When this terbium (Tb)- labeled antibody is paired with baculovirus-mediated (BacMam) expression of a Histone H3-GFP fusion protein, the TR-FRET readout enables sensitive detection of H3 lysine 4 dimethylation. The resulting high-throughput screening (HTS) compatible assay can be used to identify inhibitors of methyltransferases and demethylases acting on lysine 4 of histone H3 in the cell type of your choice.

LanthaScreen® Tb-anti-Histone H3K4me2 Antibody Lets You:

• Identify more relevant inhibitors since the methyl transferases and demethylases are in their natural protein complexes
• Conserve precious cell samples with the miniaturizable homogenous assay format
• Improve data quality with the advantages of TR-FRET

Get More Physiologically Relevant Results
The LanthaScreen® Histone H3K4me2 antibody allows for the investigation of dimethylation at lysine 4 on histone H3. This enables screening for potential inhibitors of methyl transferases and demethylases associated with Lys4 dimethylation in their natural complexes in a physiologically relevant cell type.

BacMam and LanthaScreen® Convenience Saves Sample and Time
Assays are run in a fully homogenous, addition-only format without any of the washing, lysate transfer, or separation procedures required for traditional methods such as Western blotting and ELISA, making it ideal for HTS applications. By using the same BacMam reagent for GFP-Histone H3, other histone H3 modifications (Ph, Me, Ac) can be monitored just be exchanging the Terbium (Tb) labeled antibody. In addition, the application of the LanthaScreen® technology includes all of the advantages of TR-FRET detection including reduced data noise, less interference from fluorescent compounds, and high sensitivity, allowing the use of fewer cells than traditional Western or ELISA methods.
