Figure 5From: Efficient and reproducible generation of high-expressing, stable human cell lines without need for antibiotic selectionGlycoanalyses of hAAT. Proteins from cell culture medium of amniocyte cell pool Z171-5A were treated with increasing amounts of (A) PNGaseF or with (B) Neuraminidase and fractionated on SDS-containing polyacrylamide gels. Upon transfer on nitrocellulose Western Blot analyses were performed using a monoclonal anti-hAAT antibody. For controls hAAT purified from human plasma was used. (C) A- and B-type oligosaccharide chains of hAAT and cut positions of PNGaseF and Neuraminidase.Back to article page
