Proceedings of the National Academy of Sciences USA 94(23), 12297–12302 (11 November 1997), DOI 10.1073/pnas.94.23.12297. Exact full first bylines Richard W Roberts and Jack W Szostak. Abstract and introductory rationale describe puromycin-mediated RNA-peptide fusions linking a peptide to its encoding mRNA; immunoprecipitation enriched an encoded myc epitope peptide from random fusion material.

Additional exact locator: Selective Enrichment of an RNA-Peptide Fusion and Figure 5, pmc.ncbi.nlm.nih.gov/articles/PMC24913/ . Before/after anti-myc immunoprecipitation aliquots were reverse-transcribed and PCR-amplified with a radiolabeled primer; restriction digestion distinguished the myc encoding sequence from the pool. The figure also notes preferential translation/reverse transcription, so recovered sequence ratios are not automatically unbiased input ratios.

Science 249(4968), 505–510 (3 August 1990), DOI 10.1126/science.2200121. Primary indexed bylines C Tuerk and L Gold, retained without inferring full given names. Abstract describes alternating RNA-binding selection and amplification, with an eight-base randomized region giving 65,536 possible sequences.

Additional primary abstract observation: two selected RNA sequences, one the wild type and one differing at four positions, had equivalent binding constants to T4 DNA polymerase. This supports the distinction between sequence identity and measured binding function. pubmed.ncbi.nlm.nih.gov/2200121/ .

Andreas Schroeder and colleagues, BMC Molecular Biology 7, article 3, 31 January 2006; DOI 10.1186/1471-2199-7-3. The Abstract, Feature selection, Discussion and Figure 8 describe a learned multi-feature score from RNA electrophoresis traces rather than a single ribosomal-peak ratio. The scale runs from 1 to 10, with larger values assigned to better integrity. The score is not a direct fraction of intact molecules. First-author spelling follows the original byline; no identification with similarly named mathematicians is made.

Additional locators: Table 1 partitions 1339 electropherograms into 937 training and 402 test records.
