COA Handling Instructions

Dopamine is a catecholamine neurotransmitter that is produced in the substantia nigra, ventral tegmental area, and hypothalamus of the brain. Dopamine plays several important roles in the brain and body. Dopamine acts through D2 dopamine receptors to induce endocytosis of VEGFR2, which is critical for promoting angiogenesis.

Description

Dopamine is a catecholamine neurotransmitter that is produced in the substantia nigra, ventral tegmental area, and hypothalamus of the brain. Dopamine plays several important roles in the brain and body[1]. Dopamine acts through D2 dopamine receptors to induce endocytosis of VEGFR2, which is critical for promoting angiogenesis[1].

D2 Dopamine Receptor

 

In Vitro

Vascular permeability factor/vascular endothelial growth factor (VPF/VEGF) strongly stimulates human umbilical vein endothelial cells (HUVECs) proliferation. The stimulatory effect of VPF/VEGF is abrogated by Dopamine (1 μM; 24hours)[2].

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

Cell Proliferation Assay[2]

Cell Line: HUVECs
Concentration: 1 µM
Incubation Time: 24 hours
Result: Inhibited VPF/VEGF-induced HUVEC proliferation specifically through its D2 receptor.
In Vivo

Dopamine (50 mg/kg; i.p. injection; days 1-7) strongly and selectively inhibits the vascular permeabilizing and angiogenic activities of VPF/VEGF[2].

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

Animal Model: Syngeneic C3Heb/FeJ mice with MOT ascites tumors[2]
Dosage: 50 mg/kg
Administration: I.p. injection; 7 days
Result: Corresponding to ~5% of the median lethal dose (LD50) in mice) beginning at 24 hours after tumor-cell injection and continuing daily for 7 days.

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

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (16.32 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.

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.
 If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

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.
