35,000 cells were plated on XF96 polystyrene cell culture microplates (Seahorse®, Agilent, CA, USA) 24 h before the experiment. For the KD experiments, cells were transfected in 10 cm dishes over-night and seeded on XF96 polystyrene cell culture microplates 24 h before the experiment. Thirty minutes before the measurement, cell medium was changed to XF assay medium supplemented with 1 mM sodium pyruvate, 2 mM glutamine and 5.5 mM D-glucose and incubated in non-CO2 37 °C incubator. Prior to loading the plate, XF assay media was refreshed and Ca2+ free assay media was added to respective wells. XF96 extracellular flux analyzer was used to measure oxygen consumption rate (OCR) and extracellular acidification rate (ECAR). OCR (pmol O2/min) and ECAR (mpH/min) values were normalized to protein content. For the rescue, ECAR was assessed following injection of 25 µl 7x Ca2+ buffer after basal ECAR in 0 Ca2+ was measured. Protein concentration of each well was determined with the PierceTM BCA Protein Assay Kit (Thermo Scientific, Rockford, IL, USA).

One day before the experiment cells were plated on XF96 polystyrene cell culture microplates (Seahorse®, Agilent, CA, USA). They had to be 100% confluent on the day of the experiment. Before the measurement cells were washed and incubated in XF assay medium supplemented with 1 mM sodium pyruvate, 2 mM glutamine and 5.5 mM D-glucose. An XF96 extracellular flux analyzer was used to measure oxygen consumption rate (OCR) and extracellular acidification rate (ECAR).

Cells were plated in XF96 polystyrene cell culture microplates (Seahorse Bioscience) at a density of 30,000 cells per well. After an overnight incubation, cells were washed and preincubated for 30 minutes in unbuffered XF assay medium (Seahorse Bioscience) supplemented with 5.5 mM d-glucose and 1 mM sodium pyruvate at 37°C in a non-CO2 environment. Oxygen consumption rates were subsequently measured using an XF96 extracellular flux analyzer.

iBACs were plated in XF96 polystyrene cell culture microplates (Seahorse Bioscience®, Agilent, Santa Clara, CA, USA) at a density of 10,000 cells per well and differentiated to mature adipocytes. Pretreatment with inhibitors was performed for 2 h with the following concentrations: 40 μM atglistatin [31 ], 100 nM bafilomycin A1 (Merck, Darmstadt, Germany), and 40 μM chloroquine (Merck, Darmstadt, Germany). All inhibitors and 10 μM isoproterenol (Merck, Darmstadt, Germany) were present during the 30 min equilibration in unbuffered XF assay medium (Seahorse Bioscience®, Agilent, Santa Clara, CA, USA) supplemented with 5.5–25 mM d-glucose, 2 mM glutamine and 1 mM sodium pyruvate at 37 °C in a non-CO2 environment and during measurement. Oxygen consumption rate was subsequently measured every 7 min using an XF96 extracellular flux analyzer (Seahorse Bioscience, Agilent, Santa Clara, CA, USA). Optimal concentrations of specific inhibitors/accelerators of the electron transport chain were determined in a prior titration experiments and used as followed: 2 μM oligomycin, 0.3 μM carbonyl-cyanide p-trifluoromethoxyphenylhydrazone, 2.5 μM antimycin A (all reagents form Merck, Darmstadt, Germany). Results were normalized to protein concentration determined by BCA assay (Thermo Fisher Scientific, Waltham, MA, USA) and presented as pmol O2/(min × μg protein).

Measuring Mitochondrial Respiration in C2C12 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
C2C12 cells were seeded in XF96 polystyrene cell culture microplates (Seahorse Bioscience) at a density of 25.000 cells per well. 24 h after plating, cells were washed and preincubated for 30 min in serum-free XF assay medium supplemented with D-glucose (25 mM), sodium pyruvate (1 mM) and glutamine (2 mM) at 37°C in a non-CO2 environment. Oxygen consumption rate (OCR) was subsequently measured every 7 min using an XF96 extracellular flux analyzer (Seahorse Bioscience). 2.5 μM antimycin A was used to stop mitochondrial respiration (= non-mitochondrial respiration). Basal mitochondrial oxygen consumption rate (OCR) was calculated by subtracting average of 3 subsequent non-mitochondrial OCRs from average of three basal OCRs (prior to antimycin treatment) and normalized to individual protein amount (pmol O2/(min x protein per well)).
For CB-839 treatment, 60,000 C2C12 cells were seeded in XF24-well plates and allowed to adhere overnight. The next day, wells were washed twice with PBS and serum-free, pyruvate-free DMEM, in the presence or absence of 1μM CB-839 (or 0.01% DMSO). 6 hours after treatment, OCRs were measured as described above and subsequently normalized to cell counts and OCRs of individual genotype (control versus AGC1-KD) in DMSO treated conditions.

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.
