Historically, ligand binding assay techniques were used extensively to quantify hormone or hormone receptor concentrations in plasma or in tissue. The ligand-binding assay methodology quantified the concentration of the hormone in the test material by comparing the effects of the test sample to the results of varying amounts of known protein (ligand). The foundations for which ligand binding assay have been built are a result of Karl Landsteiner, i… Web14 apr. 2024 · Estrogen-receptor-positive breast cancer accounts for the majority of breast cancer cases, and they are predominantly treated with endocrine therapy .

We then showed that an impermeable form of E 2 , namely E 2 :BSA, mimics E 2 effects suggesting a role for the membranous G-protein …
Bivalent ligands consist of two drug-like molecules (pharmacophores or ligands) connected by an inert linker. There are various kinds of bivalent ligands and are often classified based on what the pharmacophores target. Homobivalent ligands target two of the same receptor types. Heterobivalent ligands target two different receptor types. Bitopic ligands target an orthosteric binding sites and allosteric binding sites on the same receptor.
