Antisera directed against the cytoplasmic portion of human erythrocyte Band 3 were used to follow the degradation of the band 3 molecule. Small amounts of Band 3 were degraded when well-washed red cell membrane ghosts were incubated in the cold; this process was greatly accelerated by incubating ghosts at 37°C. Band 3 labeled with pyridoxal-phosphate was(More)
A micro-space cell culture system was recently developed in which cells such as hepatocytes can be cultured and formed into a multicellular three-dimensional (3D) architecture. In this study, we assessed the performance of HepG2 cells cultured in this micro-space cell culture system in a drug toxicity test, and evaluated the effects of micro-space culture(More)

This unit describes a collection of methods for chemical labeling of carbohydrates (free oligosaccharides or oligosaccharides conjugated to proteins, peptides, or lipids) by oxidation followed by reduction or by direct reduction. Oligosaccharides can be labeled with either radioisotopes or nonradioactive fluorescent molecules. These labelings allow one to(More)

This unit describes release of oligosaccharides that are attached to polypeptides through an N-acetylgalactosamine (GalNAc) linkage to the hydroxyl groups of serine or threonine. The beta-elimination procedures described here can be used to recover the oligosaccharide chains (also called glycans) and/or identify the serine or threonine residues involved in(More)
