Cell Assay
[2]

Diazoxide is dissolved in DMSO to prepare 50 mM stock solution. NSC-34 cells are allowed to differentiate for 8 weeks under reduced serum conditions and then seeded in 24-well plates. Glutamate is dissolved in culture medium and added to cultures at concentration of 10 μM for 24 h. Cell treatment with 100 μM diazoxide starts 2 h before glutamate exposure. Cell viability is measured by the MTT assay[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[3][4]

Rats: Adult male Sprague-Dawley rats with induced cerebral ischemia (n=10 per group) receive an intraperitoneal injection of 0.1% DMSO (1?mL; vehicle group), diazoxide (10?mg/kg; DZ group), or diazoxide (10?mg/kg) plus 5-hydroxydecanoate (5?mg/kg; DZ + 5-HD group) 30?min after CPR. The control group (sham group, n=5) undergoes sham operation, without cardiac arrest. Mitochondrial respiratory control rate (RCR) is determined. Brain cell apoptosis is assessed using TUNEL staining. Expression of Bcl-2, Bax, and protein kinase C epsilon (PKCε) in the cerebral cortex is determined by Western blotting and immunohistochemistry[3].

Mouse: Diazoxide is prepared by diluting a 100 mM stock solution in 10% polyethoxylated castor oil in PBS. In C57BL/6 wild-type and Kir6.2(?/?) mice, a 5 μL drop of 5 mM diazoxide is topically administered to one eye of each mouse while the fellow control eye received vehicle (DMSO and 10% polyethoxylated castor oil in the same proportion as the treated eye). IOP is measured daily at 1 hour, 4 hours, and 23 hours following treatment. Treatment with diazoxide and vehicle is continued daily for 14 consecutive days[4].

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.
