To compare dystrophin quantification techniques across multiple institutions to determine the most reliable methods and assess their biological utility for clinical trials.
Five expert laboratories analyzed a single reference set of normal and dystrophinopathy muscle biopsies using quantitative immunohistochemistry and Western blotting.
Standardized protocols were established to assess inter- and intralaboratory variability across a broad range of dystrophin expression levels.
Measurements across laboratories demonstrated high concordance with minimal inter- and intralaboratory variability, with quantitative immunohistochemistry displaying greater sensitivity than Western blotting.
Data showed strong agreement between quantitative immunohistochemistry and Western blotting, and mean dystrophin estimates were highly consistent across alternative immunohistochemistry methods.
