In Vivo

DPDPE (70 or 140 nM; i.c.v.; once) shows anticonvulsant effects in rats^[1].
DPDPE (0.78–25 μg/mouse; i.c.v.; once) enhances bicuculline-induced convulsions in mouse^[2].

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

Animal Model:

Male Sprague-Dawley rats (225-275 g)^[1]
Dosage:

70 or 140 nM followed by a 2 μl saline flush
Administration:

Intracerebroventricular injection
Result:

Resulted in a significant, dose-dependent increase in the convulsive threshold to flurothyl.

Animal Model:

Male ddY mice weighing 20–30 g, pretreated with 1.5 mg/kg bicuculline (subcutaneous injection)^[2].
Dosage:

0.78–25 μg/mouse, once
Administration:

Intracerebroventricular injection
Result:

Caused a dose-dependent increase in the proportion of mice exhibiting convulsions.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
