S-100 <strong>Protein</strong> Interacting Drugs 335<br />

Fig. 5. Affinity chromatography of recombinant S-100A1 (wild-type and C-terminal<br />

88 FFWENS 93 deletion mutant) on a Fluphenazine-Sepharose column. Ca 2+ , sample<br />

loading followed by washing with the Ca 2+ -containing buffer (Buffer B); EGTA, addition<br />

of the buffer containing 2 mM EGTA (Buffer C); urea, addition of the buffer<br />

containing 6 M urea (Buffer D).<br />

4. Notes<br />

1. Epoxy-activated Toyopearl 650M can be used to couple Amlexanox through its<br />

amino group. However, the extent of nonspecific binding to the gel is higher than<br />

that of Amlexanox coupled AF-amino Toyopearl.
