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

Biological Activity
GIP, rat TFA (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 TFA 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.
