Abstract

Sucrose-derived RNA fractions transferring specific delayed sensitivity in vitro were extracted from mono-(p-azobenzenearsonate)-N-chloracetyl-l-tyrosine (ARSNAT)- or keyhole limpet hemocyanin (KLH)-sensitized guinea pigs. Fractions having biological activity were assessed by acrylamide gel analysis to enumerate the number of RNA species in active fractions, and to compare and examine the banding patterns of each RNA fraction. Each isolated B fraction of RNA exhibited multiple bands of RNA with molecular weights ranging from 4.0 × 105 to 8.5× 105. Depending on the source and antigen sensitivity of the RNA donor, several differences were observed among the analyzed fractions. These were bands of varying intensity, presence of additional RNA bands, absence of bands in certain positions, and RNA bands migrating in different positions on the gels. Acrylamide gel analysis separation, and resolution of B fractions with specific immunobiological activity now offers an approach for further isolation and resolution of the active species.
