...s of rats. The drug inhibited the normal passage of potassium ions into and out of heart cells through pores in the cell membrane known as delayed rectifier potassium channels, the study showed. The adverse effects of drugs like Celebrex and Vioxx based on their selective inhibition of COX-2 currently...Potential Key to Brain Blood-Flow Disorders Explored by Scientists

...spindle fibers can produce force that moves the chromosomes toward the poles of the cell during mitosis or meiosis. In 1957, Inou added a polarization rectifier to his custom-built microscope, which dramatically decreased distortion and improved the contrast of the image. Rudolf Oldenbourg further improved the...Flexible nanoantenna arrays capture abundant solar energy

Today's rectifiers ca...ifiers that go with our nanoantennas," says Kotter, noting that a nanoscale rectifier would need to be about 1,000 times smaller than current commercial devices ...Anti-Potassium Channel, Inward Rectifier Kir2.1 Polyclonal Antibody, Unconjugated from CHEMICON
Description: Recognizes Kir2.1 protein. The epitope is specific for Kir2.1 and is not present in any other known protein. SPECIES REACTIVITIES: The immunogen sequence is identical in rabbit, bovine, porcine and guinea pig. It is highly homologous in rat and mouse (17/19 residues) and chick (15/19 residues). ...Anti-Potassium Channel, Inward Rectifier Kir4.1 Polyclonal Antibody, Unconjugated from CHEMICON
Description: Recognizes Kir4.1. The epitope does not share homology with any other known proteins. SPECIES REACTIVITIES: The antibody is also expected to work with mouse and human due to sequence homology. Other species have not been tested....
