    Sulpiride purchased from MedChemExpress. Usage Cited in: Mol Psychiatry. 2025 Dec 12.  [Abstract]

    Peak frequency analysis of calcium traces retrieved from spontaneously active ALN and NGN2 neurons after 24 h treatment with DMSO (solvent control), 10 µM of Pramipexole dihydrochloride (DRD2 agonist) or 10 µM of Sulpiride (DRD2 antagonist).

    Sulpiride purchased from MedChemExpress. Usage Cited in: Acta Pharmacol Sin. 2024 Nov;45(11):2253-2266.  [Abstract]

    Experimental timeline and schematic of NOR test to examine the role of Sulpiride (D2R antagonist) on ORM retrieval in saline- and METH-treated mice. Saline or METH (2 mg/kg, i.p.) was injected 30 min before the test; simultaneously, saline or Sulpiride (0.25 μg/side) was microinfused bilaterally into PrL.

    Sulpiride purchased from MedChemExpress. Usage Cited in: Acta Pharmacol Sin. 2024 Nov;45(11):2253-2266.  [Abstract]

    Bilateral infusion of Sulpiride (0.25 μg/side) effectively reversed the ORM retrieval impairment. In addition, the exploration time of novel object C compared with familiar object A was not significantly different in the Saline + Sulpiride (0.25 μg/side) group, while PI was decreased compared with the Saline + Saline group.

    Sulpiride purchased from MedChemExpress. Usage Cited in: Nat Methods. 2024 Apr;21(4):680-691.  [Abstract]

    Normalized fluorescence change in gDA3m to indicated compounds (1 μM). Sulpiride (Sulp), D2R antagonist. n = 3 wells with 500-600 cells per well.

    Sulpiride purchased from MedChemExpress. Usage Cited in: Nat Methods. 2024 Apr;21(4):680-691.  [Abstract]

    Activation of endogenous D2Rs by the D2-specific agonist quinpirole decreased the stimulus-evoked change in gDA3m fluorescence, reflecting presynaptic inhibition via D2 autoreceptors; this decrease was reversed by the addition of D2R antagonist Sulpiride (Sulp), and adding the D1R-specific antagonist SCH abolished the stimulation-evoked response.

    In Vivo:

    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

    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.
