    Cell Assay
    [1]

    To analyse inhibition of histone methylation in MV4-11 cells following Pinometostat treatment, extracted histones (400 ng) are fractionated on a 10-20% Tris HCl gels with Tris-Glycine SDS running buffer under denaturing conditions and transferred to nitrocellulose filters. Filters are cut into strips and incubated for 1 hour in blocking buffer at room temperature (RT) and then incubated overnight at 4°C in blocking buffer. Filters are washed 3 times for 5 minutes with wash buffer (Phosphate buffered saline (PBS) including 0.01% Tween 20 (PBST)) and incubated with infrared tagged secondary antibody at RT for 1 hour. Filters are washed in PBST and reprobed for 1 hour at RT with the appropriate total histone antibody control (mouse anti-histone H3 (1:20,000), CST 3638, or mouse anti-histone H4 (1:10,000), CST 2935). Filters are washed again in PBST and incubated with infrared tagged secondary antibody (IRDye 800Cw donkey-anti-mouse IgG (1:20,000), Li-Cor 926-32212) at RT for 1 hour. After a final ish in PBST, filters are scanned using the Odyssey infared imager (Li-cor). To analyse inhibition of H3K79 methylation in peripheral blood mononuclear cells (PBMCs) from rats dosed with Pinometostat (EPZ-5676), 20 μL of PBMC whole cell lysate is fractionated on denaturing gels and analysed by immunoblotting with antibodies to H3K79me2 or total H3. Signal intensities specific for the H3K79me2 antibody and total histone H3 control antibody are quantified using Odyssey software. The H3K79me2 signal intensity is normalized by dividing it by the total histone H3 control signal intensity in the same lane.

    Animal Administration
    [1]

    0.2 mL of a MV4-11 cell suspension (1×107 cells) in PBS is injected subcutaneously into female athymic nude mice (Crl:NU(Ncr)-Foxn1nu). Tumors are measured by calipers and mice are randomized according to tumor size into treatment groups (n=10) before the initiation of dosing with Pinometostat (EPZ-5676) when tumor volumes reache approximately 100 mma3. Pinometostat is administered intraperitoneally three times daily for 28 days at 10 and 20 mg/kg in 10% ethanol in saline. Mice are weighed and tumors measured with calipers twice weekly until the end of the study.

    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.
