|Description||BRD4770 is a histone methyltransferase G9a inhibitor with IC50 of 6.3 μM, and induces cell senescence.|
BRD4770 reduces cellular levels of di- and trimethylated H3K9 via inhibition of G9a, induces senescence, and inhibits both anchorage-dependent and -independent proliferation in the pancreatic cancer cell line PANC-1.  The combination of gossypol and BRD4770 increases LC3-II levels and the autophagosome number, and thus acts in synergy to induce cell death in PANC-1 cells. 
Biochemical activity of G9a:Dissociation Enhanced Lanthanide Fluoro-ImmunoAssays (DELFIA) are performed in white, opaque 384-well plates coated with Neutravidin. Test compounds are diluted to 12 μg/mL in 50mM Tris-HCl pH 8.5 containing 4% DMSO and 10 μL is dispensed into the wells. Blank and control wells received only compound buffer. GST-G9a at 10 μg/mL and SAM at 40 μM are diluted in 50mM Tris HCl pH 8.5/10 mM DTT and added in a volume of 20 μL. Blank wells receives Tris/DTT buffer only. The reactions are initiated by the addition of 800 nM H3(1-20)-cysbiotin substrate in 50 mM Tris pH 8.5 in a volume of 10 μl, and incubated at room temperature for 60 minutes. The plates are washed 3 times with 100 μl of Wash Buffer (50mM Tris pH 7.4, 150 mM NaCl, 0.05% Tween 20, 0.2% BSA). Next, 50 μl of Fluoroimmunoassay (FI) Buffer (50 mM Tris HCl pH 7.8, 150 mM NaCl, 0.05% Tween 40, 25 μM DTPA, 0.2% BSA, 0.05% BGG) containing 5ng α-2X-di-meth H3-K9 and 5ng goat anti-rabbit Eu chelate is added to all wells of the plate, and the plate is incubated for an additional hour at room temperature. The plates are washed 3 times with 100 μL of Wash Buffer, and 50 μL of Enhancement Solution is added to each well. Time resolved fluorescence is measured after 45 minutes on a Viewlux Microplate Imager imaging for 15 seconds with a 354 μs window, 400 μs delay, excitation at 360 nm, and emission at 618 nm.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
