Scalable production and biophysical characterization of an enzyme cocktail derived from human red blood cells.
Article in Biotechnology progress. 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
Red blood cells (RBCs) play a critical role in oxygen and carbon dioxide transport, which is facilitated by RBC-encapsulated hemoglobin (Hb) and carbonic anhydrase (CA). In addition, RBCs are constantly exposed to oxidative stress due to the intracellular reactive oxygen species (ROS) generated during Hb auto-oxidation. Antioxidant enzymes within RBCs, such as superoxide dismutase (SOD), catalase (CAT), and peroxiredoxin (Prx), counteract ROS generation to protect the RBC from oxidative stress. Therefore, this study presents a scaled-up method to extract an enzyme cocktail from lysed human RBCs, enriched with the major RBC enzymes with minimal Hb contamination. Using ethanol-chloroform precipitation and multiple biophysical analyses (SDS-PAGE, SEC-HPLC, MALDI-TOF, and LC-MS/MS), the RBC enzymes were successfully separated from Hb in the hemolysate. The purified enzyme cocktail exhibited minimal Hb contamination and retained a significant amount of CA, and antioxidative enzymes like SOD and CAT. Therefore, this scalable RBC enzyme purification method provides an efficient approach for isolating RBC enzymes with broad biomedical relevance.
