Figure 2From: Isoforms of Retinol binding protein 4 (RBP4) are increased in chronic diseases of the kidney but not of the liverRepresentative MALDI spectra of RBP4 in a healthy control, a chronic liver disease (CLD) patient and a chronic kidney disease (CKD) patient. Control and CLD patient show the non-truncated RBP4 (1 = 21.065 Da) and the RBP4-L peak (2 = 20.950 Da) whereas the RBP4-LL peak (3 = 20.837 Da) is solely present in the CKD patient.Back to article page
