Provided is an organic tin-free cationic electrodeposition coating composition which does not contain organic tin compound and can sustain a superior coating curability under currently used baking conditions, and to a catalyst for the composition. A catalyst for electrodeposition coating composition containing a bismuth compound (A), wherein: the bismuth compound is a compound having a ligand prepared from a &#x3b2;-diketone represented by Chemical Formula (1) is provided. (wherein, a plurality of Rare the same or different from each other and represent a hydrocarbon group, and a number of total carbon atoms in two Ris 4 or larger)

Electrodeposition coating material composition and catalyst for electrodeposition coating material

In one embodiment of the present invention, a composition is disclosed for measuring a binding affinity between a nucleic acid and a test substance, which contains an organic fluorescent substance capable of binding to an RNA and which emits fluorescence having an intensity greater while the organic fluorescent substance is liberated from an RNA than while the organic fluorescent substance is bound to an RNA. This enables a highly accurate and easy measurement of a binding affinity between a test substance and a nucleic acid, and allows various substances to be examined as a test substance.
