(n.) A small glass tube, often with an enlargement or bulb in the middle, and usually graduated, -- used for transferring or delivering measured quantities.
Example Sentences:
(1) With NaCl as the major constituent of the bathing solution (potassium-free pipette and external solutions) the reversal potential (Er) of the noradrenaline-evoked current was about 0 mV.
(2) Sickle and normal discocytes both showed membrane elasticity with reversion to original cell shape following release of the cell from its aspirated position at the pipette tip.
(3) The minimum contraction produced by the threshold current involved usually three or four, sometimes two, sarcomers on both sides of the injecting pipette but contraction involving only one sarcomere was not observered.
(4) In the cell-attached (CA) configuration, the presence of isoguvacine (3-5 microM) in the pipette solution triggered the opening of channels displaying multiple current levels.
(5) Spermine potentiation showed fast on-off kinetics, and intracellular spermine, loaded in the recording pipette, did not occlude potentiation by extracellularly applied spermine.
(6) The channels usually ceased conducting within a few minutes after seal formation with the patch pipette and could not be re-activated with depolarizing voltage steps.
(7) When added to the pipette solution and introduced by cell dialysis, trypsin had no effect on whole cell IK, even when significant effects on the amplitude and kinetics of ICa were evident.
(8) The voltage-dependent K+ current, IM (M-current), was maintained by including MgATP in the pipette solution and by buffering the solution pH to 6.7.
(9) The PGCs were picked up with a fine glass pipette, and one hundred were then injected into the terminal sinuses of 2-day-old Japanese quail embryos (24 somites); bubbles were then inserted to prevent haemorrhage.
(10) Accordingly, this method allows rapid and direct recording of channels in the SL membrane without first having to pretreat fibers with proteolytic enzymes to render the SL accessible to patch pipettes.
(11) Whole-cell ICa free of other overlapping currents was recorded with a suction pipette.
(12) To stop the arteriolar flow and allow perfusion pressure, as set by a mercury manometer, to be built up in the lumen of the vessel, the glomerulus was sucked into a constriction pipette.
(13) The recording cylinder, located a known distance from the pipette tip, picks up a continuous, large-amplitude, multiunit response which can be used to accurately position the tip according to physiological criteria.
(14) Membrane responses were recorded by a patch pipette technique in cultured cells isolated from rat portal vein.
(15) Since the collected epithelium cells adhere to the pipettes, these cells were transferred onto a polycarbonate filter by using a micro spatula.
(16) HRP is probably only taken up by damaged fibers so that the amount of fibers labeled is determined by the extent of the lesion caused by the injection pipette.
(17) This prolongation was prevented in standard whole cell recordings when the pipette solution contained 0.5 mM EGTA.
(18) Single thalamocortical axons were recorded extracellularly in the white matter by using horseradish-peroxidase-filled pipettes.
(19) pipette fillers and latex gloves, were found to be the source of these and other compounds in the reagent blank profile.
(20) The placement of the GABA-containing pipette did not appear to be responsible for the observed variation, since vertical repositioning of the pipette did not alter the slope of the charge-response relationship.
