WebDespite the introduction of alternative protein assays, the Bradford method remains a popular technique, with the original article (1) being cited over 3,500 times in primary research papers in 2006, thirty years after its initial publication. The Bradford assay relies on the binding of the dye Coomassie Blue G250 to protein. WebThe procedure for Bradford protein assay is very easy and simple to follow. It is done in one step where the Bradford reagent is added to a test tube along with the sample. After mixing well, the mixture almost immediately changes to a blue color.

However, LBAs require suitable capture and detection reagents, which may not be readily available, especially in drug discovery and early development. 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… curly cane
