一般描述
The utilization of ion-pairing reagents as mobile phase additives allows the elution of ionic and highly polar substances using reversed phase HPLC columns. The purity of mobile phase additives is a prime factor to their successful application. Sigma-Aldrich offers an outstanding collection of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) analyzes. All mobile phase additives are rigorously tested with special emphasis on the requirements of modern reversed phase HPLC:

In this study we show that the potassium-channel blocker tetrahexyl ammonium chloride (THA+) is able to inhibit inositol 1,4,5-trisphosphate (InsP3)-induced calcium release in an apparently biphasic fashion with a IC50 of 3 microM. This inhibition was not alleviated by valinomycin

Effects of tetraalkylammonium ions, having tetraalkyl chains of increasing length from ethyl to octyl, on inositol-trisphosphate (InsP3)-induced Ca2+ release and contractile mechanics were examined in guinea-pig skinned ileal smooth muscle longitudinal strips. Although tetrahexylammonium ions (THexA) appeared to be the
