A Northwestern University postdoctoral researcher found problematic image manipulations in marketing materials for more than 17,000 commercial antibodies, Ars Technica reports. The article says the alterations ranged from background-noise removal to copied-and-pasted data that fabricated results. Antibodies are widely used in biological research to identify proteins, tissues and cellular characteristics, so performance images can influence researchers' selection of commercial reagents. The account follows an initial discovery in May involving some suppliers' experimental images.
