EMBO reports (2005) 5, 812–817. 10.1038/sj.embor.7400190
Due to a calibration error, the UVA doses presented by P. Gulati et al in the August 2004 issue of EMBO Reports were 20.4-fold too low. The UVA lamp has been recalibrated with a new UV Lightmeter (UV-340, Lutron, Taiwan). Despite this correction, the doses of UVA inducing the calpain-dependent cleavage of protein tyrosine phosphatases are still in the range of physiological exposure.
