| Product Description | Product Introduction Alamar Blue detection reagent provides a simple, rapid, reliable and safe method for cell proliferation and cytotoxicity detection, which is suitable for high-throughput detection experiments. The main component of the detection reagent is a redox indicator. In the oxidized state, it appears purple-blue and non-fluorescent, while in the reduced state, it turns into a reduction product with pink or red fluorescence, with an absorption peak of 530-560nm and an emission peak of 590nm. In the process of cell proliferation, the ratios of NADPH/NADP, FADH/FAD, FMNH/FMN and NADH/NAD in the cell increase and are in a reducing environment. The dye taken into the cell is reduced by these metabolic intermediates and cytochromes and then released outside the cell and dissolved in the culture medium, changing the culture medium from non-fluorescent indigo blue to fluorescent pink. Finally, use an ordinary spectrophotometer or fluorophotometer for detection, and the absorbance and fluorescence intensity are proportional to the number of active cells. Instructions 1. Add 10µl of detection reagent to 100µl of cell suspension, and incubate in a cell incubator for 2-6 hours. The color of the medium changes from indigo blue to pink and you can proceed to the next step. 2. It is recommended to use a fluorescence microplate reader for detection, the excitation light wavelength is between 530-560 nm, the emission light wavelength is 590 nm, and the relative fluorescence unit (RFU) is recorded. 3. Draw a standard curve or cell growth curve: the ordinate (Y axis) is the relative fluorescence unit (RFU); the abscissa (X axis) is the cell number or time point or drug concentration. Precautions 1. The appropriate density of cells can increase the detection sensitivity. For 96-well plates, we recommend seeding 100 microliters of cells per well. The cell concentration range is: 100-10,000/well for adherent cells, 2,000-50,000/well for suspension cells, and medium as a blank control. For 384-well plates, the cell concentration and seeding volume are both halved. 2. The whole process should be aseptic operation, because microbial contaminants can also reduce the detection reagents and affect the experimental results. 3. Pay attention to the concentration of inoculated cells and the incubation time after adding detection reagents. If the cell concentration is too high or the incubation time is too long, it will cause a secondary reduction reaction, resulting in colorlessness and disappearance of fluorescence. 4. When incubating, avoid light. 5. This product can use fluorescence or spectrophotometric detection, but the sensitivity of fluorescence is high, and the experimental error is small. Fluorescence detection is recommended. |
