Description

Alarelin acetate is a synthetic GnRH agonist.

In Vitro

The cell viability in the presence of alarelin was significantly lower than that in the absence of alarelin. The maximum stimulatory effect on cell viability was achieved at a concentration of 10-5 M and it acted in a dose-dependent manner[1]

In Vivo

Alarelin could inhibit the gastric acid secretion both by direct actions on parietal cells in rats and by inhibiting vagous function[2]. Alarelin could significantly enhance ratio of G1 phase and decrease ratio of S phase of GSMC of rats[1].

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: ≥ 2.08 mg/mL (1.62 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: ≥ 2.08 mg/mL (1.62 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

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.

Cell Assay
[1]

The cells are trypsinized in a solution of 2.5 g/L trypsin and seeded in a 96-well plate. After the cells are grown for 24 h to approximately 800 g/L subconfluent state, 0.1 mL medium containing 2.5% calf serum and various concentrations (0.001, 0.1, 10 μM) of alarelin is added to each well, respectively, and incubated for 24 h in a CO2 incubator. Each concentration is tested in at least 12 wells. Briefly, 15 μL of MTT solution is added to each well and incubated for 4 h. Then, the medium and MTT are removed and 150 μL of DMSO is added to each well and shaken for 10 min to dissolve the crystal. The OD is determined at 490 nm using an ELISA reader[1].

Animal Administration
[2]

Rats: Male Sprague-Dawley rats are divided into two groups. In Group I: Gastric acid secretion is measured in a chambered stomach. Briefly, the abdomen is incised, and both the stomach and duodemun are exposed and tied respectively; then 1.5 mL 0.9% sodium chloride (containing Alarelin, 2 μg/kg) is infused into the each chambered stomach. After 15, 30, 45, 60 min, the gastric juice is drew out of the chambered stomach and the pH is measured in the ABL-500 respectively. The control is infused saline instead of Alarelin. In Group II: After anaesthetized, 2 mL Alarelin (2 μg/kg) is administered into the tail vein. The control is injected the saline instead of Alarelin. Then, the stomach and duodenum are tied and infused 1.5 mL saline immediately. After 15, 30, 45, 60 min, the gastric juice is also drew out of the chambered stomach and the pH is measured in the ABL-500 respectively[2].

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.
