The authors of “Production and characterization of monoclonal anti-sphingosine-1-phosphate antibodies” (J. Lipid Res. 50: 2245–2257) have advised the Journal that the name of an oligo stated in the Materials and Methods section of their manuscript is incorrect. The mouse immunoglobulin kappa chain variable region (VL) was amplified by PCR using VK20, not MKV20.
This incorrect oligo name initially appeared online but has since been corrected.
