Since the resin matrix is a crosslinked, hence insoluble, styrene-divinylbenzene copolymer, its molecular weight cannot be determined and thus the supplier does not provide any data regarding MW.
With the help of Gaussian software one can find out the DNA interaction of molecule theoretically. Can anyone help me perform the calculation?
