|---|---|---|
| cut open oocyte voltage clamp assay | OBI_0002184 | [The cut-open oocyte Vaseline gap (COVG) voltage-clamp technique is designed to solve weaknesses in the two elextrode voltage clamp by maximizing the benefits of the Xenopus oocyte expression system by improving on clamp speed, signal-to-noise ratio, and ability to effectively perfuse the oocyte. In this way, it was possible to combine the most popular transient expression system, and the associated benefits of molecular cloning and site-directed mutagenesis, with the superior voltage-clamp properties of cut-open cell techniques.] |
| current clamp assay | OBI_0002185 | [The current clamp technique records the membrane potential by injecting current into a cell through the recording electrode. Unlike in the voltage clamp mode, where the membrane potential is held at a level determined by the experimenter, in "current clamp" mode the membrane potential is free to vary, and the amplifier records whatever voltage the cell generates on its own or as a result of stimulation. This technique is used to study how a cell responds when electric current enters a cell; this is important for instance for understanding how neurons respond to neurotransmitters that act by opening membrane ion channels.] |
| administering substance in vivo | OBI_0600007 | [A process by which a substance is intentionally given to an organism resulting in exposure of the organism to that substance.] |
| electroencephalography | OBI_0002186 | [An extracellular electrophysiology assay where electrodes are mounted outside the brain (either on the surface of the scalp on onto the brain surface itself during surgery) to measure the electrical field over the external surface.] |
| extracellular electrophysiology recording assay | OBI_0000454 | [An electrophysiology recording assay where the recording location of the electrode is extracellular] |
| single-unit recording | OBI_0002187 | [An extracellular electrophysiology assay where a single microelectrode is placed in close proximity to a single neuron to measure voltage and current changes over time. This is the technicque used by Hubel and Wiesel to measure firing properties of primary visual cortex neurons in the 1950s in their original Nobel-prize winning study. A classic, old technique.] |
| multi-unit recording | OBI_0002188 | [An extracellular electrophysiology assay where a collection of microelectrodes (often in an 'array' configuration) is placed into neural tissue to measure the distribution of voltage and current changes for a population of cells over time.] |
| local field potential recording | OBI_0002189 | [An extracellular electrophysiology assay where a microelectrode is placed in the extracellular space of brain tissue to measure action potential and compared to an electrode either outside or inside that tissue.] |
| ribonuclease U2 | PR_000025475 | [A protein that is a translation product of the Ustilago sphaerogena RNU2 gene or a 1:1 ortholog thereof.] |
| courier organization | OBI_0002190 | [An organization that delivers messages, packages, and mail.] |
| ribonuclease CL3 (chicken) | PR_000025478 | [A protein with ribonuclease activity that is purified from chicken liver.] |
| courier tracking number | OBI_0002191 | [A centrally registered identifier symbol assigned by a courier organization in order to track the delivery of an item.] |
| Leica Peloris rapid tissue processor | OBI_0002192 | [An automatic tissue processor that is a dual retort tissue processor manufactured by the Leica company to provide fast, high quality tissue processing for histology laboratories.] |
| automatic tissue processor | OBI_0001064 | [A device for processing histological tissue having a tissue carrier basket suspended from a turntable overlying a plurality of beakers suspended from a carrier plate. The turntable is raised, indexed, and lowered by a suitable driving mechanism to move the tissue basket sequentially through the beakers. Timers can each be programmed to control the movement of the turntable to provide various different cycles for processing the tissue. Some of the beakers are received in individual thermal baths to heat and control the temperature of the substances received in the beakers for treating the tissue.] |
| ribonuclease V1 (cobra) | PR_000025477 | [A protein with ribonuclease activity that is a constituent of cobra venom.] |
| Microm Ergostar HM200 | OBI_0002194 | [A microtome that is manufactured by Microm and uses a vertical cutting stroke common to all rotary microtomes engaged by a horizontal sliding movement. An operating arm replaces the handwheel and is attached to both sides of the instrument for greater convenience to permit control of sectioning from the left or right.] |
| microtome blade | OBI_0002195 | [A device that is the part of a microtome used to slice specimens to a desired thickness.] |
| Sakura Low profile Accu-Edge microtome blade | OBI_0002196 | [A microtome blade that is manufactured by Feather and is disposable. The ultra-sharp blades section specimens without striations, distortion or chattering.] |
| tissue section thickness | OBI_0002197 | [A length measurement datum that is the result of an assay measuring the thickness of a tissue section.] |
| length measurement datum | IAO_0000408 | [A scalar measurement datum that is the result of measurement of length quality] |
