An endothelial cell inhibitor was purified from supernatant of an Epstein-Barr virus-immortalized cell line and identified as fragments of calreticulin. The purified recombinant NH2-terminal domain of calreticulin (amino acids 1-180) inhibited the proliferation of endothelial cells, but not cells of other lineages, and suppressed angiogenesis in vivo.

The DNA binding domain (DBD) of poly(ADP-ribose) polymerase (PARP) has proved to be a novel, highly sensitive probe for detecting DNA breaks in intact cells undergoing apoptosis. A recombinant peptide spanning the DNA binding domain of PARP was expressed, purified and used to detect DNA strand breaks in fixed cells. Fluorescence microscopy with this probe(More)
