The Seahorse assays were performed in Seahorse XF DMEM supplemented with glucose to a final concentration of 10 mmol/L, sodium pyruvate to 1 mmol/L, and l ‐glutamine to 2 mmol/L. Pancreatic islets are scarce, and isolating sufficient mitochondria from them is difficult. The Seahorse XF24 instrument was recently developed as a multi-well plate-based assay platform that uses fluorescent optode detectors to measure oxygen consumption rates (OCR) and extracellular acid release (ECAR) from cells plated in custom 24-well plates. Seahorse-based mitochondrial respiration assay on primary cortical neurons or mitochondria purified from wt or α-syn null mice. Recently it was discovered that the lysosomal V-ATPase, which is known to induce apoptosis, interferes with lipid metabolism in cancer, yet the interplay … 103260-100 and Cat No. The evaluation of mitochondrial proton leak by Seahorse assay is indirect, as it is based on the oxygen consumption rate. Two milligrams of mitochondria per assay were used, and 40 μM pulses of CaCl 2 were continually given until mitochondrial Ca 2+ uptake no longer occurred or the mitochondria underwent MPT as evidenced by irreversible increase in Calcium Green-5N fluorescence, which was saturated in the presence of 40 μM alamethicin (arrowhead). Mitochondria and homogenates were loaded into Seahorse XF96 microplate in 20 μl of MAS containing substrates. Elevated mitochondrial biogenesis and/or metabolism are distinguishing features of cancer cells, as well as Cancer Stem Cells (CSCs), which are involved in tumor initiation, metastatic dissemination, and therapy resistance. pone-0085436-g001: The Seahorse assay.Oxygen consumption rate (OCR) is measured before and after the addition of inhibitors to derive several parameters of mitochondrial respiration. Although cells can be offered various substrates in the assay medium, many cell types can oxidize stored pools of energy substrates. The experiment was performed as explained in Section 5. CONTRACT RESEARCH SERVICES. In addition, there are no high-throughput real-time assays that assess mitochondrial function. Mitochondrial Architecture.
