An investigation has found that Thermo Fisher Scientific, a major supplier of laboratory reagents, has manipulated images in its antibody verification data, with over 100 images showing signs of manipulation. The images, which are supposed to demonstrate the effectiveness of the antibodies, feature identical bands, conspicuous brushstrokes, and repetitive blocks of background noise. The manipulation of these images raises concerns about the reliability of the data and the potential impact on scientific research. The company has responded, stating that it takes scientific integrity seriously and will ensure that website users are informed if images have been optimized for presentation and clarity.
