体外実験

The embryonic ectoderm development (EED) protein is an essential subunit of Polycomb repressive complex 2 (PRC2). A-395 antagonizes of the H3K27me3 binding functions of EED. A-395 binds to EED in the H3K27me3-binding pocket, thereby preventing allosteric activation of the catalytic activity of PRC2. A-395 is capable of competing for H3K27me3 peptide binding to EED, with an IC50 of 7 nM. A-395, but not the close chemical analog A-395N, modulates activity of PRC2 in cells by potently reducing the H3K27 methyl mark in a highly selective manner. A-395 treatment inhibits both H3K27me2 and H3K27me3, with IC50 values of 390 nM and 90 nM, respectively. Furthermore, A-395 treatment results in growth inhibition of human tumor cell lines sensitive to SAM-competitive EZH2 inhibitors[1].

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 0.83 mg/mL (1.71 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 0.83 mg/mL (1.71 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.83 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (8.3 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
