Descripciòn

Glucagon (19-29), human is a potent and efficient inhibitor of insulin secretion.

IC₅₀ & Target

Insulin secretion^[1]

In Vitro

Glucagon (19-29), from 0.1 pM to 1 nM, exerts a potent negative inotropic action. The most striking observation is a 45% increase in the amplitude of cell contractility elicited by the combination of 30 nM glucagon with 1 nM Glucagon (19-29)^[3].

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

In Vivo

Glucagon (19-29), also named Miniglucagon, is the COOH-terminal (19-29) fragment processed from glucagon. Glucagon (19-29) dose-dependently inhibits insulin secretion stimulated by 8.3 M glucose, with no change in the perfusion flow rate. A concentration of 1 nM Glucagon (19-29) has a significant inhibitory effect on a 1 nM glucagon-like peptide 1 (7-36) amide–potentiated insulin secretion^[1]. Glucagon (19-29) is a highly potent and efficient inhibitor of insulin release by closing, via hyperpolarization, voltage-dependent Ca²⁺ channels linked to a pathway involving a pertussis toxin-sensitive G protein^[2].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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 (1.85 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 (1.85 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 (1.85 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.

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

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.

Administraciòn de animales
^[1]

Rats^[1]

To test the effect of miniglucagon (Glucagon (19-29)) on stimulated insulin secretion, 8.3 mM glucose is perfused during the experiments, including a 45-min equilibration period, followed by miniglucagon (1, 10, 100, and 1,000 pM) perfused with or without 1 nM tGLP-1. To study the glucagon and miniglucagon secretion, the glucose concentration is switched from 11 to 3 mM after a 45-min stabilization period, and the peptides secreted are measured by radioimmunoassay^[1].
