This study identifies SLC26A11 as a dual-function protein that acts as both a sulfate transporter and a chloride channel, with implications for treating brain edema and lysosomal storage diseases.

The paper develops a mass-spectrometry-based method to absolutely quantify fluorescent protein fusions and estimate their mature chromophore fraction, validated through a case study on expression kinetics.

The paper introduces GEQO biosensors for absolute analyte quantification in single cells without requiring specialized equipment, showing they account for buffering and retain time trace information.
