title: Alterations in iodinated cell surface proteins during myogenesis.
abstract: Lactoperoxidase catalysed iodination was used to label surface proteins of chick embryo muscle cells during myogenesis. Both quantitative and qualitative changes were observed between 125I-labelled surface proteins of pre-fusion, mid-fusion, and post-fusion cells. Significantly, two bands at 245,000 molecular weight were present at pre-fusion but were observed as a single band at mid- and post-fusion. Radioactivity in this band increased selectively at post-fusion with a concomitant increase in lower molecular weight labelled proteins.
