Complement receptor activity of recombinant porcine CR1-like protein expressed in a eukaryotic system.
Article in Immunologic research, 2016. 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
Primate complement receptor type 1 (CR1) protein, a single-chain transmembrane glycoprotein, plays an important role in immune adherence and clearing complement-opsonized immune complexes. Here, the mRNA of the porcine primate-like complement receptor (CR1-like) gene was analyzed, and two domain sequences with potential functions were cloned into the pwPICZalpha vector for expression in Pichia pastoris. The recombinant proteins were purified with both Protein Pure Ni-NTA resin and strong anion exchange resin. The activities of the purified recombinant proteins were evaluated by SDS-PAGE, western blotting, and complement receptor assays. The results indicated that two domains of the CR1-like protein, CCP36 and CCP811 with molecular weights of 29.8 kDa and 30 kDa, respectively, were successfully expressed in P. pastoris. These two recombinant proteins possess some of the functions of the primate CR1 protein. Using these two proteins coupled with an antibody blocking technique, we also showed that CR1-like is expressed on natural porcine erythrocytes.
