Ordering Information

Biological Activity

Lanthanum(III) chloride is an inorganic compound that acts as a blocker of divalent cation channels, primarily calcium channels. By inhibiting calcium influx through voltage-gated and store-operated calcium pathways, it disrupts intracellular calcium homeostasis and downstream calcium-dependent signaling cascades. This blockade attenuates intracellular calcium transients, thereby modulating excitation-contraction coupling in muscle cells and neurotransmitter release in neuronal systems. [1]

All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 50 mg/mL (134.63 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
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).
