Principle Of Resazurin Reduction Assay
The assay relies on the conversion of non-fluorescent resazurin into intensely fluorescent resorufin by mitochondrial dehydrogenases in living cells. Metabolically active cells reduce resazurin, producing a measurable signal proportional to cell number and health. TriBioScience formulates this reagent for consistent fluorescence and minimal batch variation across experiments.
Workflow And Handling Guidelines
Add the resazurin solution directly to adherent or suspension cells at the desired final concentration. Incubate under standard cell culture conditions for the recommended time, then read fluorescence using a plate reader. The kit compatibility with common media reduces the need for washing or sample transfer steps.
Data Analysis And Standard Curves
Generate a standard curve using known cell numbers or a reference viability condition to convert fluorescence intensity into absolute cell counts. Normalize treated samples to untreated controls to quantify growth inhibition or cytotoxicity. TriBioScience includes validation data to support comparability across different instruments and operators.
Applications In Research And Quality Control
Use this resazurin cell viability kit tribioscience for cytotoxicity screening, compound potency testing, and assessing cell health over time. The low-toxicity profile allows downstream recovery of cells if required. Consistent performance supports reproducible results in multi-well formats and high-throughput settings.
Best Practices For Reliable Viability Measurements
- Use untreated cultures as viability controls for each experimental condition.
- Include triplicate or higher replicates to capture biological and technical variability.
- Verify linearity of the fluorescence signal across the expected cell number range.
- Document incubation times and environmental conditions to support cross-experiment comparisons.
- Validate protocol performance when switching cell lines or culture media.
FAQ
Reader questions
Can I use this kit with primary neurons without washing steps?
Yes, the resazurin solution can be added directly to neuron cultures, and the no-wash protocol minimizes disturbance while maintaining fluorescence accuracy.
How long can the TribioScience resazurin reagent be stored after opening?
When stored at 4°C protected from light, the reagent remains stable for the duration specified by the batch label, typically several weeks without significant signal loss.
Is this kit suitable for high-content imaging systems? Yes, the fluorescent read mode and compatibility with multi-well plates make it ideal for high-content imaging platforms that require sensitive viability readouts. Do I need to calibrate the plate reader between different batches of the kit?
Standardize instrument settings across batches, and include a positive control well to verify consistent performance; calibration is typically unnecessary if reader parameters remain unchanged.
