GIP, rat
Based on 1 Customer Validation
GIP, rat is a bioactive peptide derived from rats. GIP, rat inhibits GIP-mediated postprandial insulin release as well as GIP-promoted glucose uptake in the upper small intestine. GIP, rat can be used in research related to insulin resistance, glucose intolerance, and type 2 diabetes.

Activité biologique
Description
In Vitro
GIP, rat (4 h) stimulates cAMP-dependent β-galactosidase production in LGIPR2 cells, with maximum activity observed at a concentration of 10-8 M following 4 h of incubation[5].
GIP, rat binds to GIP receptors on stably transfected L293 cells with an IC50 of 7 nM[5].

Animal Model:Wistar (male, 250-350 g, fasted for 20 h prior to experimentation, anesthetized with sodium pentobarbital)[3]
-
Dosage:0.9 μg immunoreactive rat GIP·kg-1·h-1
-
Administration:i.v.; continuous infusion; 90 minutes
-
Result:Nearly doubled glucose-induced insulin release, with plasma insulin reaching 178 mU/l at 30 minutes and 171 mU/l at 90 minutes.
Trebled integrated 90-minute insulin response (13.67 mU/mL vs. 4.52 mU/mL for glucose alone).
Significantly reduced integrated 90-minute glucose response (0.28 mol/l vs. 0.53 mol/l for glucose alone).
Raised peak plasma immunoreactive GIP from a basal level of 239 pg/mL to 983 pg/mL at 30 minutes.

Solvant et solubilité
In Vitro:
DMSO : 25 mg/mL (5.00 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (0.50 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (0.50 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.
