Thermo Fisher Scientific BacMam Histone H3K27me3 Cellular Assay Kit

Invitrogen™ BacMam Histone H3K27me3 Cellular Assay Kit

The BacMam Histone H3K27me3 Cellular Assay is a high-throughput screening (HTS) compatible TR-FRET assay for the interrogation of trimethylation at lysine 27 on histone H3 in a cellular format. Baculovirus-mediated gene delivery (BacMam) provides a convenient tool for the expression of GFP-Histone H3 fusion protein in your cell background of interest. Coupled with a terbium (Tb)-labeled site-specific antibody, the resulting cellular assay can be used to identify inhibitors of methyltransferases and demethylases acting on lysine 27 of histone H3.

The kit includes

• BacMam Histone H3 Reagent
• LanthaScreen™ Tb-anti-histone H3K27me3 Antibody
• 6X LanthaScreen™ Cellular Lysis Buffer
• Instrument Control Terbium TR-FRET kit

With the BacMam Histone H3K27me3 Cellular Assay Kit You Can

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

Get More Physiologically Relevant Results

The BacMam Histone H3K27me3 Cellular Assay allows the investigation of trimethylation at lysine 27 on histone H3 with your choice of cellular backgrounds including primary cells. This enables screening for potential inhibitors of methyl transferases and demethylases associated with Lys27 trimethylation in their natural complexes in a physiologically relevant cell type.

BacMam and LanthaScreen™ Convenience Saves Sample and Time

Assays are run in a fully homogeneous, addition-only format without any washing, lysate transfer, or separation procedures required for traditional methods such as Western blotting and ELISA, making them ideal for HTS applications. By using the same BacMam reagent for GFP-Histone H3, other histone H3 modifications (Ph, Me, Ac) can be monitored simply by exchanging the Terbium (Tb)-labeled antibody. The LanthaScreen™ technology provides 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.
