ABSTRACT:
The present invention is directed to a multi-domain oligonucleotide ligand having multiple functions conferred by each of the domains. The ligand is bound to a solid phase matrix for use in both mRNA-affinity chromatography and as a priming matrix for generating matrix-bound cDNA from the mRNA bound to the matrix. The resultant cDNA was tested and found to function as a solid-phase template for PCR. This solid-phase template approach to PCR is demonstrated with oligo-d(T) paper. The functional domains are defined by polynucleotide sequences on the ligand to confer the different functions.
