Characterization of Low Molecular Weight Variants (Fragmentation) in Pichia pastoris by CE-SDS.
Article in Methods in molecular biology (Clifton, N.J.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Komagataella phaffii is an efficient system for secreted recombinant protein expression. However, this host also expresses native proteases whose activity can degrade the target proteins, thus impacting native yield and quality. This proteolysis creates impurities considered critical quality attributes (CQAs) by regulatory agencies. Capillary electrophoresis sodium dodecyl sulfate (CE-SDS) is an ideal analytical method for characterizing these impurities due to its high resolution, sensitivity, and ability to separate protein fragments, making it valuable for the control strategy and characterization of a biopharmaceutical product.
