Description: Methacholine chloride is a cholinergic agonist and parasympathomimetic bronchoconstrictor. A metabolically stable analog of acetylcholine. Its ability to constrict airway smooth muscle is used to assess bronchial reactivity in the laboratory and clinically.
Methacholine is primarily used to diagnose bronchial hyperreactivity, which is the hallmark of asthma and also occurs in chronic obstructive pulmonary disease. Acetyl-β-methylcholine (methacholine), an analog of acetylcholine, is use as a receptor agonist to study processes such as airway hyperresponsiveness associated with asthma.
Metabolically stable analog of acetylcholine; muscarinic agonist. Its ability to constrict airway smooth muscle is used to assess bronchial reactivity in the laboratory and clinically.

Catalog Number: (PRSI91-408)
Supplier: ProSci Inc.
Description: Chitinase-3-Like Protein 1 (CHI3L1) belongs to the glycosyl hydrolase 18 family. CHI3L1 is expressed in activated macrophages, articular chondrocytes, synovial cells as well as in liver. It lacks chitinase activity and is secreted by activated macrophages, chondrocytes, neutrophils and synovial cells. CHI3L1 is thought to play a role in defense against pathogens, or in tissue remodeling, and in the capacity of cells to respond to and cope with changes in their environment. In addition, CHI3L1 is associated with susceptibility to asthma-related traits type 7 (ASRT7) which assessed by methacholine challenge test, serum IgE levels, atopy, and atopic dermatitis.
