Biological Activity
Sal003 is a cell-permeable inhibitor of eIF2α phosphatase that prevents the dephosphorylation of eukaryotic initiation factor 2α (eIF2α). By maintaining eIF2α in its phosphorylated state, Sal003 suppresses general protein translation initiation while promoting endoplasmic reticulum stress signaling and modulating synaptic plasticity. This inhibition elevates cellular levels of phosphorylated eIF2α and influences translation-dependent cellular phenotypes. [1]

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).
Pre-aliquoted for Longevity: Solid-state aliquots offer longer shelf life compared to stock solutions.
