A quantitative spectrophotometric assay for N-hydroxysuccinimide and its esters based on the formation of a chromophore upon titration with mild base has been developed. The maximum absorbance for the chromophore is at 260 nm with an extinction coefficient of 9700 M-' cm-'. The method can be used fo
to labeled biotin results in an inhibition of the signal Biotinylated recombinant aequorin was used in the generated by the label (3-8). The higher the amount development of a heterogeneous bioluminescence of free biotin present, the less labeled biotin is bound binding assay for biotin. This assay
