Ordering Information

Biological Activity

Bumetanide is a loop diuretic that acts as a selective inhibitor of the Na+-K+-2Cl- cotransporter 1 (NKCC1) and weakly inhibits NKCC2. By suppressing NKCC-mediated transmembrane transport of sodium, potassium, and chloride ions, bumetanide disrupts intracellular ion homeostasis and osmotic balance. This inhibition impairs downstream intracellular chloride accumulation and cell volume regulation, leading to altered cellular excitability and electrolyte transport mechanisms. [1]

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).
