Description	(-)-Bicuculline methochloride (#B-137) is a highly pure, synthetic, and biologically active compound.
Molecular Formula	C21H20ClNO6.
Background	(-)-Bicuculline methochloride is a synthetic compound that acts as water soluble GABA(A) receptor antagonist. The compound is a quaternary salt of bicuculline (BIC), a competitive antagonist of the GABA(A) receptors. (-)-Bicuculline methochloride is more stable at physiological pH and more soluble in aqueous solutions than bicuculline. The compound was shown to affect other neurotransmitter systems such as the cholinergic system1.GABA(A) receptors are members of the Cys-loop superfamily of ligand-gated ion channels. They mediate GABA (gamma-aminobutyric acid) action, a major inhibitory neurotransmitter, through the central nervous system (CNS). They play an important role in inhibiting cell excitation in the CNS. They are considered to be a major target of antiseizure drugs2,3.
Shipping	Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks. For longer periods, it should be stored at -20°C
Concentration	1-10 uM.
Reconstitution	Centrifuge the vial before adding solvent (10,000 x g for 5 minutes) to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. Avoid vigorous vortexing. Light vortexing for up to 3 seconds is acceptable if needed. For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in sterile water at a concentration of at least 0.1 mg/mL. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. It is recommended to prepare fresh solutions in working buffers just before use. Repeat freeze-thawing may result in loss of activity
