Binding of soluble muIfnar-2 to type I IFN.
(A) Table showing the specific binding of 32P-muIFNα1 to 5 ng/μL and 10 ng/μL recombinant muIfnar-2 ECD. Data are expressed as the mean ± SD cpm. (B) Histogram showing the elution profile of total 32P-muIFNα1 bound to high-molecular weight complexes in serum. The mean cpm of fractions 2 to 4 were used to determine total binding (mean = 80 403 cpm), specific binding (mean = 38 440 cpm) and nonspecific binding (mean = 41 963 cpm). VO indicates void volume.
