Abstract excerpt
To reduce the immunogenicity of β-lactoglobulin (BLG), we prepared wild-type bovine BLG variant A (wt) and three site-specifically glycosylated BLGs (D28N, D137N/A139S, and P153A), and expressed them in the methylotrophic yeast Pichia pastoris by fusion of the cDNA to the sequence coding for the α-factor signal peptide from Saccharomyces cerevisiae. Sodium dodecyl sulfate polyacrylamide gel electrophoresis...
