Specificity of deoxycytidylate antibodies

Antibodies to deoxycytidylate (dpC) were elicited in rabbits using a thyroglobulin (Tg) conjugate of dpC. The specificity of the antibodies was determined by measuring the inhibition of the binding of [3H]dpC to the antibodies by various non-radioactive nucleotides or derivatives. The antibodies were found to distinguish dpC from pC and DNA from RNA, probably due to their specificity for the conformation of the deoxycytidylate.

Immunologic studies on nucleic acids and their components. I. An analysis of the specificity of anti-deoxyadenylate antibodies by a membrane-binding technique

Anti-deoxyadenylate antibodies were produced in rabbits by injecting a conjugate of deoxyadenosine 5′-phosphate with bovine serum albumin. The antisera, as analyzed by double diffusion in agar and the quantitative precipitin reaction, showed hapten-specific antibodies. The specific interaction between [3H]deoxyadenylate and antiserum was studied by a sensitive nitrocellulose membrane-binding assay. The specificity of the antibodies was analyzed by measuring the effectiveness of other nucleotides or derivatives to inhibit the hapten-antibody binding. The requirements for recognition by the antibody sites were studied by using a series of naturally occurring nucleic acid components as well as some synthetic derivatives as inhibitors. The antibodies were found to show a high degree of specificity for the whole nucleotide, the base, sugar and phosphate playing almost equally important roles. There was cross reactivity with other mononucleotides, although of a low order. The antibodies were able to react with DNA and tRNA.

Purification of antibodies for the cytokinin N6-(delta 2-isopentenyl) adenosine by affinity chromatography.

Isopentenyl adenosine antibodies useful in the investigations of the "cytokinin" functions of isopentenyl adenosine were purified by affinity chromatography. Using different affinity columns, the antibodies were purified to near complete purity. Analyses of the purified proteins revealed the presence of isopentenyl adenosine binding proteins in normal rabbit serum, which presence supports a suggested role for isopentenyl adenosine and its related compounds in animal cell division in vivo.
