Introduction:
The NRU assay testing is a reliable in vitro cytotoxicity assessment process that is continuously utilised by pharmaceutical manufacturers to analyse the safety and biocompatibility of drug substances and formulations. This method assesses the capacity of living cells to absorb and keep the neutral red dye in their lysosomes. Thus, it is a very accurate measure of cell membrane integrity and cell health overall. NRU is a very costly and effective method that is particularly used at the preclinical stage to test the APIs, excipients, and even the final dosage forms. But this technique always shows its simplicity, sensitivity, and reproducibility.
In the case of pharmaceutical companies, the NRU lab testing is very important for them to evaluate the toxicity level of the drug early, to control the quality of the drug, and to comply with the regulations set by the authorities. It aids in making better decisions by discovering possible cytotoxic effects before the clinical trials. Hence, this leads to a reduction in development risks and costs. Additionally, international guidelines and regulatory agencies have acknowledged the use of the NRU assay. Hence, it guarantees constant safety profiling, and at the same time, it enhances the reputation of the pharmaceutical products through the local and global markets.

What should you know about the Chemzin Biotox neutral red uptake testing lab?
NRU assay verification for neutral red uptake (NRU) is a method that is well recognised and accepted as in vitro cytotoxicity testing by our company, which has a high demand from the pharmaceutical industry houses. It especially assists them in continually assessing the viability and safety of medicinal ingredients and formulations during their entire process. The basis of the assay is dependent on the fact that live cells can take in and hold the neutral red dye in their lysosomes. This turned out to be a dependable measure of cellular integrity and metabolic activity.
Furthermore, we assure you that our NRU assay is very important in preclinical safety assessment, quality control, and regulatory submissions since it is the source of accurate, reproducible, and economical toxicity data. In addition to this, its conformance to international standards makes it a must-have tool for ensuring the safety of pharmaceutical products throughout the drug development process.
Step-by-step workflow for NRU assays in pharmaceutical manufacturing.
The details of our lab’s NRU assays’ step-by-step working team process are presented here in-depth.
- Cell line selection and preparation
To get the best development and the same quality throughout the production, we pick and grow mammalian cell lines that are suitable for the purpose, and this is done in a controlled environment of the laboratory.
- Sample preparation
APIs, excipients, and finished dosage forms are processed traditionally and are then available in the required concentrations.
- Cellular exposure to test samples
The adsorption of the test substances by the cells is used to judge the toxicity effect of the chemicals that are being tested.
- Neutral red dye uptake
After the exposure, a neutral red dye is introduced to the cells, which are still alive, and they will take up the dye and store it in their lysosomes.
- Washing and dye extraction
The dye that is not incorporated into the cells is washed away, and an extraction of the dye that is left within the live cells is done by using a solvent that is suitable for that purpose.
- Optical density measurement
A spectrophotometer is used to measure absorbance, which gives a quantitative representation of cell viability in particular.
- Data analysis and interpretation
The results will go through the process of being mined for cytotoxicity levels, the IC₅₀ values, and the safety profile.
- Reporting and documentation
Comprehensive reports that are regulatory-ready will help to fulfil the needs of pharmaceutical quality assurance and compliance.
Consequently, the standardised NRU assay method guarantees pharma makers’ accuracy, consistency, and proper compliance with regulations.
