The kappa-light chain sequence, submitted as the first part of Figure 6, is incorrect. This sequence actually represents an extraneous light chain, produced by the Sp2/0 myeloma cell lines that were used to make the hybridomas that ultimately expressed F1-40. We have since identified a second kappa-light chain in the F1-40–expressing hybridomas which is the actual kappa-light chain for F1-40. No other kappa-light chain has been identified in the F1-40-producing hybridomas. Please view a corrected version here:
