  • Patent number: 4240797
    Abstract: Spin labels, especially dianionic aromatic spin labels which can bind to the first specific high-affinity bilirubin-binding site on serum albumin, and which are quantitatively displaceable into solution from said site in the presence of bilirubin, can be used in an assay for bilirubin-binding capacity. In the assay, an excess of spin label is mixed with the serum albumin or serum and is titrated with standard bilirubin. ESR spectroscopy indicates a change in the rate of spin label release with addition of bilirubin, giving a value indicative of bilirubin-binding capacity. Novel dianionic aromatic spin labels are also disclosed.
