LTURM34 is a potent and selective DNA-dependent protein kinase (DNA-PK) inhibitor that exhibits high selectivity over PI3K. By inhibiting DNA-PK enzymatic activity, LTURM34 disrupts the non-homologous end joining (NHEJ) pathway responsible for repairing DNA double-strand breaks. Blockade of this repair mechanism leads to the accumulation of damaged DNA, inhibition of cell proliferation, and enhanced sensitivity to DNA-damaging treatments in cancer cells. [1][2]

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).
