Size-exclusion chromatography analysis of the interaction of FnBPB(163–480) with histone H3.
A, elution profiles of FnBPB(163–480), histone H3 alone, and a mixture of a co-incubated, equimolar concentrations of FnBPB and H3 loaded onto a Superdex 75 10/300 GL gel-filtration chromatography column. B, elution profile of a mixture of co-incubated, equimolar concentrations of FnBPB(163–480) trench mutant variant (N312A/F314A) and histone H3 loaded onto the gel-filtration chromatography column as indicated in A. In the inset, a calibration curve relating the Kav of standard proteins to their molecular mass is reported. The figure is representative of three independent experiments. mAU, milli-absorbance units.
