概要	The reaction of 5'-phosphorimidazolide of adenosine (ImpA) in the presence of Na+-V olClay (a Na +- montmorillonite) yields oligoadenylates of up to ten nucleotides in length. The scope of the ImpA reaction was investigated using a Wyoming, a Japanese, and an Otay Na+- montmorillonite. The Wyoming and Japanese clays facilitated the formation of oligoadenylates [oligo(A)] as efficiently as does VolClay. However oligomerization did not proceed in the presence of the Otay clay. The logarithmic value of the yield of each oligomeric fraction (eg. trimer, tetramer, pentamer) is inversely proportional to the length of oligomer (eg. 3, 4, 5 respectively) in those reactions where oligomers are formed. This relationship can be demonstrated by the kinetic computer simulation KINSIM.
