HS-27, a fluorescently-tethered Hsp90 inhibitor, assays surface Hsp90 expression on intact tissue specimens. HS-27 is made up of the core elements of SNX-5422, an Hsp90 inhibitor, tethered via a PEG linker to a fluorescein derivative (fluorescein isothiocyanate or FITC), that binds to ectopically expressed Hsp90. HS-27 has potential use in a see-and-treat paradigm in breast cancer[1].

HS-27, a fluorescent Hsp90 inhibitor, detects Hsp90 expression on the surface of intact tissue specimens. It consists of the core elements of SNX-5422, an Hsp90 inhibitor linked via a PEG linker to a fluorescein derivative (fluorescein isothiocyanate or FITC) that binds to peripherally expressed Hsp90 combine.

HS-27 labels all receptor subtypes of breast cancer, but not normal cells, and specifically binds to Hsp90 expressed on the surface of breast cancer cells before being internalized.
