Aggregation facilitates analysis: The Ca2+‐dependent mannose (Man) binding of the nonpeptidic carbohydrate binder pradimicin A (PRM‐A) was investigated in the solid state. The use of PRM‐A aggregates eliminated problems associated with the three‐component equilibrium. A combination of 113Cd NMR spectroscopy and 2D dipolar‐assisted rotational resonance revealed the mannose‐binding site of PRM‐A and the
