SP94
SP94 is a peptide ligand with high specificity for hepatocellular carcinoma cells. SP94 selectively binds to multiple hepatocellular carcinoma cell lines in vitro. SP94 inhibits tumor growth in a mouse model of hepatocellular carcinoma by promoting apoptosis and reducing angiogenesis. SP94 can be used as a specific probe for hepatocellular carcinoma imaging. SP94 is useful for hepatocellular carcinoma research.

Biological Activity
SP94 (40 nM of HspG41C-SM(PEG)n-SP94, 12/23 peptides/cage, 24 h) could bind selectively to HepG2 and Huh-7 cells, but does not bind to HeLa and RLN-8 cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
