1-substituted uracil and thyminederivatives have been developed. The aminolysis of 2- or 4-nitrophenyl 3-ethoxyacryloylcarbamate and 3-ethoxy-2-methylacryloylcarbamate with a variety of primary amino derivatives proceeded smoothly under very mild reaction conditions yielding almost quantitatively the 1,3-disubstituted urea derivatives. Their subsequent cyclization provided the 1-substituted uracil and thymine

Methods of producing single-stranded deoxyribonucleic acids (ssDNAs) are provided. Aspects of the methods include generating a double stranded deoxyribonucleic acid (dsDNA) and then selectively degrading one strand of the dsDNA to produce a ssDNA. ssDNAs produced using methods of the invention find use in a variety of applications, including genomic modification applications. Also provided are compositions, e.g., kits, that find use in practicing various embodiments of the invention.

Methods are provided for detecting antigen binding agents in samples. Aspects of the methods include detection of the aggregation of antigen binding agents with polynucleotide-bound antigens by sensitive proximity-based association of the antigen-bound polynucleotides. Aspects of the methods also include methods for the detection of such proximity-based association through nucleic acid amplification. In addition, compositions, e.g., reagents, kits, and devices, useful in practicing various embodiments of the methods are provided.
