Sample Use Guides

In Vivo Use Guide

In mouse models of stroke PJ34 was administered intraperitoneally at 2.5 mg/kg 2 h before onset of ischemia and 6h later. In rat studies PJ34 was administered intravenously at 10 mg/kg i.v. bolus over 3 min.

Route of Administration: Other

In Vitro Use Guide

PJ34 was evaluated in vitro in the model of stroke. For oxygen-glucose deprivation (OGD) primary neuronal cultures of cerebral cortex were incubated in a balanced solution at pO2 < 2 mmHg. PJ34 was applied to cortical cell cultures 1 h before and during OGD. Neuronal injury was quantitatively assessed by the measurement of LDH at various time points in the medium. PJ34 at concentrations abobe 30 nM attenuates neuronal cell death in cortical cultures.
