Figure 3: Glycated albumin in plasma and serum. Left panel=Coomassie blue staining of plasma proteins (Pl) that complexed with phenylboronate and were eluted with 250 mM sorbitol. Middle panel=immunoblotting with anti-albumin antibodies of albumin (Alb) and of plasma (Pl) and serum (Se) proteins that were eluted from phenylboronate. Right panel=immunoblotting with antiglycated albumin antibodies of plasma (Pl) and serum (Se) proteins that were eluted from phenylboronate. Molecular weight markers are indicated.
