1. Hardware System
Detection Channels: Operation of the detection requires an XF probe board, which is used in conjunction with a 96-well probe board. This system measures the concentration of each analyte in each well of the microplate over time and simultaneously automatically calculates the oxygen consumption rate (OCR) and proton release rate (PER) (extracellular acidification rate, ECAR).
Sensor Technology: Utilizes solid-state, fluorescent biosensors that are directly integrated into the bottom of the device. No liquid reagents are required, resulting in high stability and sensitivity.
Measurement Principle: Real-time synchronous detection of oxygen consumption rate (OCR) and extracellular acidification rate (ECAR).
Temperature Control: Precise 37°C constant temperature control system to ensure that cells are in a physiologically relevant environment throughout the experiment.
Automatic Liquid Addition: Each detection well is equipped with 4 independent reagent wells, and the instrument can automatically and precisely inject up to 4 compounds that regulate metabolism during the experiment.
Automation and Throughput: Highly automated, capable of automatically performing calibration, detection, and cleaning steps, suitable for medium to high-throughput screening.
2. Detection Performance
Detection Sensitivity: Minimal number of cells required, ranging from tens of thousands to several hundred thousand cells per well (depending on the cell type).
Measurement Speed: Can set up rapid, repetitive mixing-measurement cycles (typically each cycle lasts for several minutes), providing high time-resolution data points to capture metabolic dynamic changes.
Data Quality: Provides real-time, non-invasive kinetic data rather than a single endpoint reading.
3. Consumables
Detection Plate: Cell culture microplate.
Kit: Provides various optimized pre-prepared kits (such as XF Cell Mitochondria Stress Test Kit, XF Glycolysis Stress Test Kit), ensuring the standardization and reproducibility of the experiment.

1.Function:
The Seahorse XF Pro Cell Metabolism Analyzer can precisely analyze mitochondrial function and glycolytic function by real-time, label-free detection of the oxygen consumption rate and acidification rate of living cells and is applied in the field of cell metabolism research.
1) Real-time synchronous detection: OCR (Oxygen Consumption Rate): directly reflects mitochondrial respiratory function (electron transport chain activity). ECAR (Extracellular Acidification Rate): mainly reflects glycolytic flux (lactic acid production leading to acidification).
2) Core metabolic phenotype analysis: Through well-known Stress Test assays, reveal the complete metabolic energy profile of cells:
3) Mitochondrial stress test: by sequentially injecting multiple probe drugs, measure key parameters such as basal respiration, ATP production-related respiration, proton leakage, maximum respiratory capacity, and reserve respiratory capacity.
4) Glycolytic stress test: measure glycolytic, glycolytic capacity, glycolytic reserve, etc.
5) Cell function assessment: evaluate the metabolic adaptability and functional health status of cells under physiological, pathological or drug treatment.
2. Features:
1) While maintaining the activity and integrity of cells, real-time monitoring of their metabolic changes provides dynamic functional data.
2) Label-free, non-invasive: no need for genetic modification of cells or the use of markers (such as fluorescent dyes), avoiding possible interference to cell metabolism from these operations.
3) Highly standardized operation process: pre-designed experimental schemes and kits make complex metabolic analysis simple, reliable, and easy to repeat.
4) Extremely wide range of application fields: cancer biology, immune metabolism (such as T cell function), neuroscience, stem cell biology, aging research, etc.
