The IP3 receptor is involved in Ca2+ mobilization from intracellular stores. Recently, we purified an inositol (1,4,5)-trisphosphate receptor from rat liver plasma membrane (LPM-IP3R) [Schäfer R. Hell K. Fleischer S. (1993) Purification of an IP3 receptor from liver plasma membrane. Biophys. J. 66, A146]. The purified LPM-IP3 receptor was incorporated into(More)
1. The ether-à-go-go-related gene (erg)-like K+ current in rat lactotrophs from primary culture was characterized and compared with that in clonal rat pituitary cells (GH3/B6). The class III antiarrhythmic E-4031 known to block specifically erg K+ channels was used to isolate the erg-like current as the E-4031-sensitive current. The experiments were(More)
Antibody single-chain Fv fragment (scFv) molecules that are specific for fluorescein have been engineered with a C-terminal cysteine for a directed immobilization on a flat gold surface. Individual scFv molecules can be identified by atomic force microscopy. For selected molecules the antigen binding forces are then determined by using a tip modified with(More)
The functional role of the inward-rectifying erg-like K+ current in rat lactotrophs was studied by the use of a selective blocker, the class III antiarrhythmic agent E-4031. The erg-like current was measured as drug-sensitive current in physiological K+ gradient. In the range of the normal resting membrane potential of rat lactotrophs (around -45 mV) the(More)
About the PGA The mission of the Partnership for Geotechnical Advancement is to increase highway performance in a cost-effective manner by developing and implementing methods, materials, and technologies to solve highway construction problems in a continuing and sustainable manner.
