|Description||BAM 7 is a direct and selective activator of proapoptotic Bax with EC50 of 3.3 μM.|
|Features||Does not interact with the BH3-binding pocket of antiapoptotic proteins or proapoptotic BAK and induces cell death in a BAX-dependent fashion.|
BAM7 directly binds the previously uncharacterized BH3-binding groove at the N-terminal face of BAX. BAM7 is selective for the BH3-binding groove at the N-terminal face of BAX. BAM7 directly interacts with BAX at the very surface used by the BIM BH3 helix to trigger BAX activation. BAM7 results in functional BAX activation. BAM7 triggers the conversion of BAX from monomer to oligomer in a dose- and time-responsive manner, the kinetics of which approach saturation at a 1:8 dose ratio of BAX:BAM7. BAM7 triggers in vitro BAX oligomerization, BAX-mediated pore formation and BAX-dependent cell death. BAM7 selectively induces BAX-mediated apoptosis by triggering the hallmark features of intracellular BAX activation. BAM7 only kills the cell line that contains BAX, eliciting the biochemical and morphologic features of BAX-mediated apoptosis. 
Fluorescence polarization binding assays:Direct binding curves are first generated by incubating FITC-BIM SAHB (50 nM) with serial dilutions of fulllength BAX, BCL-XLΔC, MCL-1ΔNΔC, BFL-1/A1ΔC or BAKΔC and fluorescence polarization measured at 20 minutes on a SpectraMax M5 microplate reader. For competition assays, a serial dilution of small molecule or acetylated BIM SAHB (Ac-BIM SAHB) is combined with FITC-BIM SAHB (50 nM), followed by the addition of recombinant protein at ~EC75 concentration, as determined by the direct binding assay (BAX, BAKΔC: 500 nM; BCL-XLΔC, MCL-1ΔNΔC, BFL-1/A1ΔC: 200 nM). Fluorescence polarization is measured at 20 minutes and IC50 values calculated by nonlinear regression analysis of competitive binding curves using Prism software.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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.
