Fig. 2. Expression of wild-type and mutant forms of FcRn
chain in IMCD cells. Stable cell lines were selected after transfection of IMCD cells with cDNA encoding the
chain of wild-type or mutant FcRn. Extracts of these cells were analyzed on western blots using polyclonal rabbit antiserum against rat FcRn
chain. The two forms of FcRn detected differ in their glycosylation (see Results).
