The following article has been retracted at the request of the Authors, Editor and Publisher:
Chan C-M, Woo PCY, Lau SKP, et al. Spike Protein, S, of Human Coronavirus HKU1: Role in Viral Life Cycle and Application in Antibody Detection. Experimental Biology and Medicine. 2008;233(12):1527-1536. doi:10.3181/0806-RM-197
Concerns were raised on Pubpeer about Figure 1b which contains lanes 1 and 2 that appear to be duplicated.
The authors proactively shared the reported concerns with the Editor and explained that due to the length of time passed since this study was published, they are unable to retrieve original images or repeat the experiments on the samples originally used.
Due to the lack of uncropped, unedited images underlying figure panels, the image concerns remain unresolved. In accordance with COPE guidelines, the Experimental Biology and Medicine Editor retracts the article.
