Ordering Information

Biological Activity

INH1 is a cell-permeable Hec1 inhibitor that specifically disrupts the interaction between highly expressed in cancer protein 1 (Hec1) and NIMA-related kinase 2 (Nek2). By disrupting the Hec1/Nek2 complex, INH1 impairs kinetochore function during mitosis, leading to chromosome missegregation, spindle assembly activation, and cellular arrest. This downstream mitotic disruption effectively inhibits cancer cell proliferation and suppresses tumor growth in cellular and preclinical models.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
