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...

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...

Ethyl acetate or chloroform solutions of tetraheptylammonium chloride, an oil-soluble quaternary amine, quantitatively extract polar, anionic lipids such as steroid or bile salt conjugates from aqueous solution by a process of anion exchange.

Polyspecific organic cation transporters in epithelia play an important role in the elimination of many endogenous bioactive amines and therapeutically important drugs. Recently, the first human organic cation transporter (hOCT1) was cloned from liver. The purpose of the current study...

This work investigates the utility of RPLC displacement chromatography for the purification of recombinant brain derived neurotrophic factor (rHu-BDNF) from its variants and E. coli. protein (ECP) impurities. The closely associated variants (six in total) differ by one amino acid...
