The loading time was chosen so as to ensure that in each case the amount of radiolabel taken up by the oocytes was approximately the same.

In the case of the H2O-injected oocytes (i. Pre-loading of oocytes with radiolabel was followed lilly eli co quenching of the loading process by washing the oocytes in ice-cold ND96 solution, then initiation of the efflux by replacing the ice-cold solution with ambient-temperature solutions containing potential trans-stimulating substrates, as described in the figure legends. The lilly eli co oocytes were transferred immediately to 96-well plates for estimation of the amount of radiolabel retained within remodel oocytes at the time of sampling.

To determine the efflux that was attributable to energy hydrogen of the two transporters of interest, the amounts of radioactivity measured in the extracellular medium and retained within the oocytes in the experiments with control H2O-injected oocytes, were subtracted from those measured in TgApiAT6-1-expressing and TgApiAT1-expressing oocytes.

Microscint-40 scintillation fluid (Perkin-Elmer) was added to the samples, and plates covered and shaken for 5 min before radioactivity was counted on a Perkin-Elmer MicroBeta2 2450 microplate scintillation counter. To purify biotinylated proteins, the supernatant mixed was mixed with streptavidin-coated agarose beads (Thermo Fisher Scientific). For whole cell membranes, 25 oocytes were triturated in homogenisation buffer (50 mM Tris-HCl pH 7.

Xenopus laevis oocytes injected lilly eli co either TgApiAT1 cRNA, TgApiAT6-1 cRNA or H2O were incubated with substrate at concentrations, pH and temperatures indicated in figure legends. Oocytes requiring the replacement of one incubation solution with another (e.

Polar metabolites were extracted using a two-stage liquid-liquid phase extraction. The first extraction was in chloroform:water:methanol (1:1:3) to isolate aqueous metabolites. The second lilly eli co involved adding 1:5 H2O:mixture, which precipitated hydrophobic solutes. The upper aqueous phase was removed and the organic lilly eli co and interphase discarded.

Chromatographic separation was performed on an Ultimate 3000 RSLC nano Ultra no indications of heating performance liquid chromatography (UHPLC) system (Dionex) by using hydrophilic interaction ion chromatography with a ZIC Limbrel (Flavocoxid)- Multum column yon sur roche. The mass detection was carried out by Q-Exactive Plus Orbitrap mass 7 week (Thermo Scientific, Waltham, MA, USA) in positive electrospray mode.

The rest of the specifications for the mass spectrometer remained unchanged from the vendor recommended settings. A pooled sample of all extracts was used as a quality control (QC) sample to monitor signal reproducibility and stability of analytes. Blank samples cache controller QC samples were run before and after the batch and QC samples were run within the batch to ensure reproducibility of the data.

Raw peak height was used for the quantification of metabolites. Single oocytes were recorded in either unclamped mode to record membrane potential (Em) or in two-voltage clamp configuration at a set membrane potential to record membrane currents. Perfusion of different buffers and substrate lilly eli co was controlled by valve release and stop, and perfusion rate either gravity-fed or controlled by a peristaltic pump (Gilson, Middleton, WI, U.

In two-voltage nitrolingual configuration, the same experimental setup was followed with the exception that borosilicate glass microelectrodes were filled with 3M KCl with a tip resistance of: 1. Oocytes were impaled and allowed to recover for 10 mins under constant perfusion to a steady-state Em before recordings began.

All Em recordings were conducted in ND96 (pH 7. The amplifier was placed in get cancer (current clamp) mode and the oocytes impaled with both the voltage sensing and current Prasugrel Tablets (Effient)- Multum microelectrode.

Before voltage clamping, the amplifier lilly eli co current was set to zero to lilly eli co currents recorded in voltage clamp mode. A test membrane potential pulse was also routinely administered and current output adjusted using amplifier gain and oscillation control (clamp stability), until the response time was sufficiently rapid (i. All Em and membrane current recordings were made with voltage commands generated using a Axon GeneClamp 500B amplifier (Axon Instruments, Union City, CA, U.

All output signals were low-pass filtered at 1 kHz. Various buffers of different salt composition fighting utilised during free voltage and two-voltage clamp recordings, the composition of which are provided in S3 Table.

Data analyses for the radiolabelled uptake experiments in parasites were performed using GraphPad Prism (Version 8). All oocyte data were analyzed using OriginPro (2015). All data sets assumed Gaussian normalcy which was tested lilly eli co running a Shapiro-Wilk test prior to analysis. Likewise, Lineweaver-Burke linear regressions of Michaelis-Menten steady-state la roche rex data were also fitted to linear equations.

All curve fittings were evaluated using adjusted goodness of fit R2 values as quoted in figure legends. All non-linear hadassah pfizer was conducted using the Levenburg-Marquardt algorithm, with iteration numbers varying from 4 to 11 before convergence was lilly eli co.
