SEE ALSO...

mAChR M3 Antibody (H-4) is a mouse monoclonal IgG1 kappa light chain antibody that detects mAChR M3 of human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). anti-mAChR M3 antibody (H-4) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. The muscarinic acetylcholine receptor M3 (mAChR M3) plays a crucial role in mediating diverse cellular responses, such as the inhibition of adenylate cyclase and the modulation of ion channels, which are essential for maintaining cellular homeostasis and facilitating communication between cells. Located primarily in the central nervous system and various peripheral tissues, mAChR M3 is involved in numerous physiological processes, including smooth muscle contraction and glandular secretion. mAChR M3′s unique structure, characterized by seven transmembrane domains typical of G-protein coupled receptors, allows effective signal transduction through G-proteins, leading to the activation of downstream effector proteins. The distinct tissue distribution and functional properties of mAChR M3 highlight its importance in pharmacological research and therapeutic applications, making mAChR M3 (H-4) monoclonal antibody an invaluable tool for studying this receptor′s role in health and disease.

is this antibody compatible with murine-derived cell lines?

Asked by: Arpita
Thank you for your question. sc-518107 antibody has only been recommend for human samples. There is a 73% homology in mouse. We only recommend a species if the homology is 95% of higher .
