Clear solution
5% DMSO 95% Corn oil
0.83mg/ml Taking the 1 mL working solution as an example, add 50 μL of 16.6 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Pancuronium dibromide is a competitive nicotinic acetylcholine receptor antagonist, used as a muscle relaxant.
Targets
AChR [1]
In vitro

Pancuronium results in open channel block of embryonic-type nicotinic acetylcholine receptor channels after coapplication of blocker and acetylcholine, characterized by decrease of the time constant of current decay. Pancuronium also results in competitive block of embryonic-type nicotinic acetylcholine receptor channels. [1] Pancuronium increases heart rate, vecuronium and rocuronium produces positive inotropic effects, and vecuronium shortens refractoriness in isolated rat atria.  [2] Pancuronium (0.5 mM) induces a complete fade of the tetanic contraction while leaving the twitch unaffected in the extensor digitorum longus muscle of the rat. Pancuronium decreases the amplitude and increases the tetanic rundown of trains of endplate potentials (e.p.ps) evoked in the frequency of 50 Hz in the extensor digitorum longus muscle of the rat.[3]
In vivo

Pancuronium decreases tidal volume (VT) and minute ventilation (VE) in high dose dogs by 82%. Pancuronium decreases tidal volume (VT) and minute ventilation (VE) in low dose dogs by 40% and 55%. [4] Pancuronium limits cerebral hyperemia during prolonged seizures by attenuating increases in blood pressure as a result of elimination of skeletal muscle activity in newborn pigs. [5] Pancuronium results in a significant difference with control is observed at gallamine concentrations ranging from 0.032-0.32 mM  in tracheal smooth muscle strips from guinea-pigs.[6]
