Aptamers based sensing of pregnancy associated glycoproteins (PAG) of bovine for early pregnancy detection.

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
Tosyl activated magnetic beads were used for aptamer selection against PAG- 7 and 18 proteins of bovine origin. PAG proteins were immobilized on beads with further addition of biotin tagged aptamer library. The recognition of aptamers with PAG was identified by ST-HRP based approach which was colorimetric in nature. The selected aptamers were sequenced and at the same time several new aptamers were identified. Later M-fold structure and G-quadruplex score of aptamers were analyzed for their selection. Those aptamers having high G value and complex structure were chosen. In dot blot assay, aptamers recognized PAG protein in an animal after 42 days of artificial insemination which later given birth to a healthy calf. Further the cross reactivity with serum of 0th day animal (post AI) or with non pregnant animal serum was minimal. Aptamers have also shown interaction with PAG protein of buffalo origin. These selected aptamers have commercial application especially in development of biosensors for early detection of pregnancy in bovine.
