Seahorse xf culture plates

Manufactured by Agilent Technologies

The Seahorse XF culture plates are specialized multi-well plates designed for use with Agilent's Seahorse XF analyzers. These plates are engineered to provide a controlled and consistent environment for the cultivation and analysis of cells, tissues, or other biological samples during Seahorse XF experiments.

Mitochondrial Function Assay in Neurons

Mitochondrial function was assessed using the Seahorse Bioscience XF24 Extracellular Flux Analyzer. Neurons were plated on Seahorse XF culture plates (Seahorse Bioscience) at a density of 65,000 cells/well. On day 7, cells were rinsed in assay medium (pH 7.4) containing XF Base medium (Seahorse Bioscience), 5.5 mM glucose, and 1 mM sodium-pyruvate. Cells remained in assay medium 1 h at 37°C in a non-CO2 incubator prior to initializing the Seahorse24XF analysis. Using the MitoStress Kit as previously described [30 (link)], oxygen consumption rate (OCR) was measured under varying conditions. After three initial baseline measurements of OCR, the ATP synthase inhibitor oligomycin (1 μm) was added and three subsequent measurements were taken. Next, an electron transport chain (ETC) accelerator, p-trifluoromethoxy carbonyl cyanide phenyl hydrazone (FCCP at 1.5 μm), was added, and after 3 measurements were taken, mitochondrial inhibitors rotenone (1 μm) and antimycin (1 μm) were added, and three final measurements were taken. Data was normalized to total DNA content, which was determined from each well using the CyQuant kit (Invitrogen) as per the manufacturer's instructions.

Mitochondrial Function Assessment via Seahorse

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mitochondrial function was assessed using the Seahorse Bioscience XF24 Extracellular Flux Analyzer. Isolated mitochondria were plated on Seahorse XF culture plates (Seahorse Bioscience) at a concentration of 2ug/well with 3-4 replicate wells per animal. The plate was centrifuged for 15 minutes at 2000xg and oxygen consumption rates (OCR) were measured under varying conditions using the MitoStress Kit as previously described (Iuso 2017 (link)). After three initial baseline measurements of OCR, a saturating concentration of ADP (2mM) was added to ensure maximum state III respiration and three subsequent measurements were taken. This was followed by the addition of the ATP synthase inhibitor oligomycin (2 μM) to induce state IV respiration and three additional measurements were taken. Next an electron transport chain (ETC) accelerator carbonyl cyanide p-(trifluoromethoxy)phenylhydrazone (FCCP at 4 μM), was added to induce maximal uncoupled (state IIIu) respiration and after 3 measurements were taken, mitochondrial inhibitors rotenone (1 μM) and antimycin (1 μM) were added, and three final measurements were taken.

Evaluating Mitochondrial Function via Seahorse

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mitochondrial function was evaluated using the Seahorse Bioscience XF24 Extracellular Flux Analyzer. Isolated hippocampal mitochondria were first plated on Seahorse XF culture plates (Seahorse Bioscience) (2 μg/well) with 3–4 replicate wells per animal. The plate was then centrifuged for 15 minutes at 2000g and oxygen consumption rates (OCRs) were quantified under different conditions using the MitoStress Kit as previously described (Iuso et al., 2017 (link)). Following 3 baseline measurements of OCR (reflecting basal respiration), a saturating concentration of ADP (2 mM) was added to achieve maximum state III respiration and 3 successive measurements were taken (denoted as ADP-stimulated respiration). The ATP synthase inhibitor oligomycin (2 μm) was then added to induce state IV respiration and 3 more measurements were made. Next the electron transport chain (ETC) accelerator carbonyl cyanide p-(trifluoromethoxy)phenyl-hydrazone (FCCP at 4 μm) was added to induce maximal uncoupled (state IIIu) respiration and after 3 measurements, the mitochondrial inhibitors rotenone (1 μm) and antimycin (1 μm) were added, and 3 final measurements were made. The respiratory control ratio (RCR) between state III and state IV respiration was also calculated.

Mitochondrial Function Assessment in Alzheimer's

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mitochondrial function was assessed using the Seahorse Bioscience XF24 Extracellular Flux Analyzer. SH-SY5Y cells were plated on Seahorse XF culture plates (Seahorse Bioscience) in DMEM/F12 containing N2 growth supplement and either CAW (100ug/mL), 1,5dCQA(1.5uM) or IsoA (1.5uM), at 60,000 cells/well, which was determined to be the optimum density for basal O2 consumption rate (OCR). The following day Aβ25–35 (50uM) was added. Two days later cells were rinsed in assay medium (pH 7.4) containing XF Base medium (Seahorse Bioscience), 5.5mM glucose and 1mM sodium-pyruvate. Cells remained in assay medium 1h at 37 C in a non-CO2 incubator prior to initializing the Seahorse24XF analysis. Using the MitoStress Kit as previously described [29 (link)], OCR was measured under varying conditions. After three initial baseline measurements of OCR, the ATP synthase inhibitor oligomycin (1 μM) was added and three subsequent measurements were taken. Next an ETC accelerator, p-trifluoromethoxy carbonyl cyanide phenyl hydrazone (FCCP at 1.5 μM), was added and after 3 measurements were taken, mitochondrial inhibitors rotenone (1 μM) and antimycin (1 μM) were added, and three final measurements were taken. Data was normalized to total DNA content, which was determined from each well using the CyQuant kit (Invitrogen) as per the manufacturer’s instructions.

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.
