To elicit antibodies specific to deoxycytidylate (dpC), rabbits were immunized with dpC conjugates of the carrier proteins bovine serum albumin (BSA) and thyroglobulin (Tg). Antibodies thus formed, when analyzed by Ouchterlony-double diffusion and their binding to [3H]dpC using nitrocellulose filter assay and equilibrium dialysis, showed that the BSA conjugate of dpC is not effective, whereas the Tg conjugate of dpC (Tg-dpC) is effective in eliciting dpC specific antibodies. The antisera raised against Tg-dpC was purified on AH-sepharose-dpC and cellulose-oligo-dpC affinity columns using dpC for elution. Tg-dpC antisera could be separated into 3 fractions, namely, antibodies to Tg, antibodies specific to dpC, and antibodies to the linkage region of the carrier protein and hapten. The affinity constant for the binding of anti-dpC Fab fragments to dpC by equilibrium dialysis was $8.7 \times 10^5 M^{-1}$ at $4^0$ and $1.6 \times 10^5 M^{-1}$ at $32.5^0$. \triangle$H^0$ and \triangle$S^0$ for the binding were -10 kcal/mol and -9 cal/deg/mol, respectively.
