Applications
Standards or controls for exosome characterization.
After testing, as long as there is no handicap or there is a problem with the experimental SOP, using ContrExo® exosome standard CTE-062 for electron microscopy, particle size and WB characterization will produce a better result. Therefore, ContrExo® CTE-062 exosome standard can be used as a positive ginseng for exosome characterization experiments to conduct quality control of the experimental process. It is not limited to electron microscopy, particle size, WB three yang and one yin characterization.
Other indicators such as Yang Ginseng for CD9/CD81/CD63 positive rate testing, Yang Ginseng for HLPC-SEC purity testing, and Yang Ginseng for membrane integrity testing can be used.
Advantages
1) Worry-free purchase in stock, ready to use: There is no need for tedious and time-consuming cell culture, no need to think about how to separate large-volume supernatant-derived exosomes, no need to spend time and trouble to perform large-volume supernatant separation and purification experiments of several liters or more, and no need to worry about how to perform exosome quality control.
2) Standard 9 quality controls to achieve "touchstone" quality: appearance, pH, sterility testing, particle concentration, particle size distribution, total protein concentration, purity, TEM morphology detection, exosome protein marker WB detection;
Serial number | Parameter item: 1 | Appearance | Transparent liquid / 2 | PH | 6.8-7.4 / 3 | Sterility Test | Negative / 4 | Particle concentration | ≥3E+11 Particles/ml
