Fig. 4From: Comparison of protein profiles of the pellicle, gingival crevicular fluid, and saliva: possible origin of pellicle proteinsDetection of pellicle proteins by western blot. Samples (5 μg/lane) from pellicle, GCF, parotid gland, and mixed gland, were subjected to SDS-PAGE. Three pellicle proteins, cystatin S (a), α-amylase (b), and serotransferrin (c), were examined by western blotBack to article page
