A procedure for the preparation of oligonucleotide-peptide hybrid mole
cules by means of automated synthesis is described. The conjugates hav
e been assembled on silica supports including CPG (Controlled Pore Gla
ss) and Fractosil supports. The novel N-epsilon-lysine protecting grou
p, 1-(3,4-dimethyl-2,6-dioxocyclohex-1-ylidene) ethyl (Dde) was used.
