The cationic form of the dye, which predominates in the acidic assay reagent solution, has a λ, max of 470 nm. In contrast, the anionic form of the dye, which binds to …
A ligand binding assay (LBA) is an assay, or an analytic procedure, which relies on the binding of ligand molecules to receptors, antibodies or other macromolecules. A detection method is used to determine the presence and extent of the ligand-receptor complexes formed, and this is usually determined electrochemically or through a fluorescence detection method. This type of analytic test can be used to test for the presence of target molecules in a sample that are known to bind to th… WebApr 1, 2024 · d R L d t = B m a x L k 1 - R L L k 1 + k 2.
