The toxin AdTx1 is an orthosteric antagonist of the alpha-1A adrenergic receptor (ADRA1A) with an affinity of 0.35 nM and is 1000 times more potent on this subtype than on other adrenoceptor subtypes. It does not show interaction with other adrenergic receptors, dopaminergic receptors, histaminic receptors, muscarinic receptors, and serotoninergic receptors. AdTx1 acts as a potent relaxant of smooth muscle. Reduces prostatic muscle tone as efficiently as Tamsulosin.

Stable at room temperature, store preferably at 4°C
