摘要： Oligonucleotide sequences that mediate specific binding to thrombin and optionally contain modified bases, sugars, or sugar linkages are disclosed. Single-stranded DNA oligomers are obtained that bind thrombin and inhibit its function in vitro and in vivo. The thrombin binding oligomers are useful for therapeutic, diagnostic and manufacturing purposes. An improved method for identifying these oligomers is also described, involving complexation of the support-bound thrombin with a mixture of oligonucleotides containing random sequences under conditions wherein a complex is formed with the specifically binding sequences, but not with the other members of the oligonucleotide mixture. The thrombin-oligonucleotide complexes are then separated from both the support and the uncomplexed oligonucleotides and the complexed members of the oligonucleotide mixture are recovered from the separated complex and subsequently amplified using standard techniques.

摘要： A method for identifying oligomer sequences which specifically bind target molecules such as serum proteins, kinins, eicosanoids and extracellular proteins is described. The method is used to generate aptamers that bind to serum Factor X, thrombin, bradykinin, PGF2 alpha and cell surface molecules. The technique involves complexation of the target molecule with a mixture of oligonucleotides containing random sequences and sequences which serve as primer for PCR under conditions wherein a complex is formed with the specifically binding sequences, but not with the other members of the oligonucleotide mixture. The complex is then separated from uncomplexed oligonucleotides and the complexed members of the oligonucleotide mixture are recovered from the separated complex using the polymerase chain reaction. The recovered oligonucleotides may be sequenced, and successive rounds of selection using complexation, separation, amplification and recovery can be employed. The oligonucleotides can be used for therapeutic and diagnostic purposes.
