title: Effect of enzymatic treatments on RNP and Sm antigenic reactivities--I. Loss of RNP but increase of Sm antigenic reactivity after RNase treatment of nuclear extract.
abstract: Changes of RNP and Sm antigenic reactivities of a nuclear extract after enzymatic treatments were studied and quantified by the ELISA test. After RNase treatment of the nuclear extract, about a 300% increase of the Sm antigenic reactivity and more than a 95% decrease of RNP antigenic reactivity was found. Data from RNP-depleted nuclear extracts and column fractionation show that the increase in Sm antigenic reactivity after RNase treatment mainly comes from the RNP-Sm complex.
