Figure 4From: Interaction of Salivary alpha-Amylase and Amylase-Binding-Protein A (AbpA) of Streptococcus gordonii with Glucosyltransferase of S. gordonii and Streptococcus mutansBinding of rAbpA and amylase with GtfB. For coating antigens onto wells of ELISA plate, 4, 2, 1, 0.5, and 0.25 μg of either amylase or rAbpA were used. To each well, 1 μg of ligand protein (Gtf-B) was added.Back to article page
