1. A monoclonal antibody (mAb3) was raised against a thermo-stabilised turkey β1-adrenoceptor (β1AR-m23 StaR).
2. mAb3 was able to bind to the extracellular loop 2 of the tβ1-AR, but not its human homologue.
3. mAb3 was able to inhibit the binding of orthosteric ligands to a subset of turkey β1-receptors expressed in both CHO K1 and HEK 293 cells, and also elicited a negative allosteric effect on agonist-stimulated cAMP responses.
This article is generally reliable and trustworthy, as it provides detailed information about the research conducted and presents evidence for its claims. The authors have provided sufficient evidence for their claims, such as immunohistochemical and radioligand-binding studies that demonstrate that mAb3 was able to bind to ECL2 of the tβ1-AR, but not its human homologue. Furthermore, they have also provided evidence for their claim that mAb3 was able to inhibit the binding of orthosteric ligands to a subset of turkey β1-receptors expressed in both CHO K1 and HEK 293 cells by providing data from experiments with [3H]-CGP 12177. Additionally, they have also presented evidence for their claim that mAb3 elicited a negative allosteric effect on agonist-stimulated cAMP responses by providing data from experiments with different agonists such as alprenolol, cimaterol, furimazine, isoprenaline and propranolol.
The only potential bias in this article is that it does not present both sides equally; however this is understandable given that it is focused on one particular aspect of research. Additionally, there are no unsupported claims or missing points of consideration in this article; all claims are supported by evidence from experiments conducted by the authors. Furthermore, there are no unexplored counterarguments or promotional content present in this article; it is solely focused on presenting the results of the research conducted by the authors without any bias or agenda. Finally, possible risks are noted throughout the article where applicable; for example when discussing experiments with different agonists such as alprenolol, cimaterol, furimazine, isoprenaline and propranolol.
