Protocol

Animal experiment:

Rats[1]Male albino Wistar rats (250-350 g) are used in the assay. Following an equilibration period of 45 min, the vasoactive effect of Adrenomedullin (1-50), rat, rADM (11-50), acetylcholine (ACh), and bradykinin (BK) is evaluated. The perfusion pressure on both sides of the mesenteric circulation is increased by infusing either a sympathomimetic, methoxamine (100 μM), on the arterial side or a thromboxomimetic, U46619 (0.5 μM), on the venous side. When a plateau is reached, the agents (Adrenomedullin (1-50), rat, etc.) are administered by bolus injections (1 to 45 μL). Vasodilator responses are expressed as percent reduction of induced tone on both sides of the mesenteric vasculature. In some experiments, the effects of the CGRP1 receptor antagonist hCGRP8-37 and of the nitric oxide synthase inhibitor L-NAME are evaluated. They are infused 15 and 30 min, respectively, before the administration of the agonists[1].

Background

Adrenomedullin (1-50), rat is a 50 amino acid peptide, which induces a selective arterial vasodilation via activation of CGRP1 receptor.

Adrenomedullin (1-50), rat is a 50 amino acid peptide, which induces a selective arterial vasodilation via activation of CGRP1 receptor[1].

Adrenomedullin (1-50), rat causes a dose-dependent and endothelium-independent vasodilation on the arterial mesenteric vasculature, and this effect is inhibited by CGRP1 receptor antagonist. Adrenomedullin (1-50), rat activates CGRP1 receptor in the double-perfused mesenteric bed of the rat[1]. Adrenomedullin (1-50) ameliorates pulmonary vascular structural remodeling of hypoxic rats with incresed plasma NO and H(2)S concentrations. Adrenomedullin (1-50) also regulates the development of hypoxic pulmonary hypertension and hypoxic pulmonary vascular structural remodeling, through promoting NO and H(2)S production in hypoxic rats[2].

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
