Selective glutaraldehyde-mediated coupling of proteins to the 3'-adenine terminus of polymerase chain reaction products.
Article in Journal of biomolecular techniques : JBT, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Attachment of proteins to the 3' end of DNA increases stability of the DNA in serum and retards clearance of DNA by major organs, thereby enhancing in vivo half-life and therapeutic potential of DNA. Unfortunately, the length of DNA molecules that can be produced with 3 ' modifications by solid-phase synthesis for protein attachment is limited to 45-60 nucleotides due to uncertainties about sequence fidelity for longer oligonucleotides. Here we describe selective covalent coupling of proteins or other molecules to the 3'-adenine overhang of unlabeled and fluorophore-labeled double-stranded polymerase chain reaction products putatively at the N6 position of adenine using 2.5% glutaraldehyde at pH 6.0 and 4 degrees C for at least 16 h. Gel mobility shift analyses and fluorescence analyses of the shifted bands supported conjugate formation between double-stranded polymerase chain reaction products and beta2-microglobulin. In addition, blunt-ended DNA ladder fragments treated with glutaraldehyde at 4 degrees C showed no evidence of DNA-DNA or DNA-protein conjugate formation. With the present cold glutaraldehyde technique, longer DNA-3'-protein conjugates might be easily mass-produced. The protein portion of a DNA-3'-protein conjugate could possess functionality as well, such as receptor binding for cell entry, cytotoxicity, or opsonization.
