Seahorse XF96 Cell Assay Timing and Handling

Check if the same lab product or an alternative is used in the 5 most similar protocols

Timing: Day 2, variable, depending on the protocol

While preparing the cells for the assay and after loading the Seahorse XF96 Sensor Cartridge, the device will ask you for the Seahorse XF96 Cell Culture plate. Load the Seahorse XF96 Cell Culture plate when all incubation steps have been finished.

Run the assay.

Once the device asks you for the Seahorse XF96 Cell Culture plate, insert the plate after incubation times are completed and confirm the insertion of the plate to start the experiment.

During the experiment, the device will show you the measured values. Troubleshooting 2, 3, 4, and 5.

CRITICAL: The Incubation times of cells should not be shortened. Put the plate into the device immediately after the respective incubation times. Avoid spill over from the different wells during repetitive handling of the plates.

Seahorse XFe96 Extracellular Flux Analyser (Agilent Technologies, Billerica, MA, USA) was used to detect glycolytic capacity and cellular mitochondrial function. Measurements were performed using Seahorse Glycolysis and XF cell Mito Stress Test kits (Seahorse Bioscience, Billerica, MA, USA). Cells were seeded in an Agilent seahorse XF96 cell culture plate at a density of 4 × 104 cells per well and cultured with prepared XF medium (seahorse, 102353-100) the day before determination. The base medium, DMEM, was supplemented with 10 mM glucose, 2 mM glutamine and 2 mM pyruvate. The cell plate was placed in a non-CO2 incubator for 1 h prior to the assay. After monitoring baseline respiration, for ECAR measurement, 10 mM glucose, 2 μM oligomycin and 50 μM 2-DG were automatically injected into each well. In order, 2 μM oligomycin, 1 μM FCCP and 0.5 μM rotenone/antimycin were used to measure OCR. OCR and ECAR values were analyzed using Wave 2.6 software (Agilent Technologies) after the number of cells was renormalized.

Check if the same lab product or an alternative is used in the 5 most similar protocols
SH-SY5Y cells were plated in a V3-PS TC-treated Agilent Seahorse XF96 cell culture plate at a density of 3 × 104 cells per well. It was ensured that SH-SY5Y cells were at a passage number lower than 30 for each run. At 24 h after plating, the cells were treated with 100 ng/ml of NME1 for a duration of 48 h. The oxygen consumption rate (OCR) was measured using a Cell Mito Stress Test Kit (Cat No. 103015-100) from Agilent according to the manufacturer’s instructions using a MitoXF96 analyzer. The kit focuses on several aspects of cellular respiration using oligomycin (ATP-synthase inhibitor), FCCP (Protonophore, uncouples mitochondrial oxidative phosphorylation) and rotenone (inhibits mitochondrial complex I, thereby inhibiting mitochondrial electron transport chain). The OCR values were used to calculate basal respiration, proton leak, maximal respiration and ATP production rate. The cells were lysed in RIPA buffer after the conclusion of the assay and the protein levels were measured using bicinchoninic acid (BCA) assay ThermoFisher Scientific (Cat No. 23227) to ensure uniform protein content across groups.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
