NTA-Oligo modified with nitrilotriacetate (NTA)is a post synthesis conjugation to thiol. The thiol group can be placed at the 5' and 3' and for internal positions DTSPA can be used.

NTA-Oligo modified with nitrilotriacetate (NTA), which has high affinity to a His-tag on recombinant protein via the complexation of Ni2+.
It is a novel method to prepare a DNA-protein conjugate using histidine-tag (His-tag) chemistry.
