@xtaldave Depends on what you mean by "specific". These interactions often have some flexibility, but it's not just an ion exchange resin; the pattern of sulfates usually matters. It's rarely a case of "the more sulfo groups, the better".
@JoshuaSharp@xtaldave probably in this case it may be, I agree with Dave, I would be quite stunned to see seuquence/sulfate pattern specificity in binding to histone H3...
