In Vivo Efficacy Study

: Gabazine purchased from MedChemExpress. Usage Cited in: Nature. 2025 Oct;646(8087):1243-1253. [Abstract]; A small fraction of the currents remained in two cells, after d-AP5 exposure, presented a shape consistent with GABAA receptor-mediated currents and could be inhibited with the GABAA receptor blocker Gabazine (Gbz) (12.5 μM).

: Gabazine purchased from MedChemExpress. Usage Cited in: Elife. 2024 May 29.; The effects of ICV injection of different doses of Gabazine (2 or 4 μg/mL; 2000 nL) on the recovery time of midazolam. Compared with the vehicle, ICV injection of Gabazine could reduce the recovery time.

製品説明

Gabazine is a selective and competitive antagonist of GABA_A receptor, with an IC₅₀ of ~0.2 μM for GABA receptor.

IC₅₀ & Target

0.2 μM (GABA receptor)^[1].

体外実験

Both bicuculline and Gabazine (SR 95531) have been characterized as competitive inhibitors of GABA binding to the GABA_A receptor. Gabazine is more potent than bicuculline at blocking currents elicited by GABA, with an IC₅₀ for currents elicited by 3 μM GABA of ~0.2 μM and a Hill coefficient of 1.0. Gabazine reduces the currents elicited by 10 μM alphaxalone by ~30%, for responses of receptors containing wildtype β2 subunits. The concentration of Gabazine requires producing half the maximal block is ~0.2 μM. Gabazine also could only produce a partial block of currents gated by 300 μM pentobarbital. The maximal reduction, again, is ~30%, and the concentration of Gabazine required to produce half the maximal block is ~0.15 μM^[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: ≥ 2.5 mg/mL (6.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (6.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (6.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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: PBS
Solubility: 7.14 mg/mL (19.39 mM); Clear solution; Need ultrasonic and warming and heat to 60°C

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.
