Phentolamine hydrochloride (Sigma, P7547), nadolol (Sigma, N1892), atenolol (Sigma, A7655), and ICI-118,551 hydrochloride (SelleckChem, 0821), were used in this study as antagonists for different adrenergic receptors and were dissolved in milliQ water and filter-sterilized. Three different ADRB2 agonists were used. Norepinephrine bitartrate (Sigma, A0937) was dissolved in complete IMDM supplemented with 10% FBS. Albuterol (Salbutamol sulfate, SelleckChem, S2507) was dissolved in either DMSO (Fig. 2C) or complete IMDM supplemented with 10% FBS (all others). Salmeterol (Tocris, 1660) was dissolved in DMSO. The α7 nicotinic acetylcholine receptor antagonist, methyllycaconitine, was dissolved in milliQ water. Forskolin was dissolved in DMSO and used to stimulate cAMP production. The corresponding vehicle control was used for each experiment.

Isometric Tension Measurement in Airway Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
ASM-024 was provided by Asmacure Ltée. ASM-024, methacholine (Methapharm Inc.) and salbutamol (Ventolin, GlaxoSmithKline) were solubilized in appropriate aqueous solution. Formoterol (LKT Laboratories Inc.) and salmeterol (Tocris) were diluted in DMSO. Tissues and cells were exposed to 0.1 to 0.5% DMSO. Isometric tensions were acquired with the data acquisition System MP150 (Biopac Systems) via an isometric force transducer (Harvard apparatus). The data were digitalized and analyzed with AcqKnowledge 3.7.3 software.
This study was carried out in strict accordance with the recommendations in the Guide for the Care and Use of Laboratory Animals of the Canadian Council on Animal Care (CCAC) regarding acclimation, environmental enrichment, and analgesic and anesthesia procedures. The protocols were approved by the Committee on the Ethics of Animal Experiments of Université Laval. In two experiments, tissues from human donors were obtained after written informed consent in accordance with an Internal Review Board-approved protocol at IUCPQ Research Center (Institut universitaire de cardiologie et de pneumologie de Québec) in Québec, QC (Canada).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
