Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

The role of the ubiquitin-proteasome pathway in the formation of mallory bodies.

Bardag-Gorce F, van Leeuwen FW, Nguyen V, French BA, Li J, Riley N, McPhaul LW, Lue YH, French SW

The dynamics of Mallory body (MB) formation are difficult to follow in vivo. Because of the lack of an in vitro mouse hepatocyte culture model, a cellular extract approach was developed. In this model an immunoprecipitate was obtained using an antibody to cytokeratin-8 (CK-8). The isolate contained a large number of compounds: CK-8, ubiquitin, a frameshift mutation of ubiquitin (UBB(+1)), ... [more]
