Problem
The coupling experience of fluorescence and the spray film, preservation and treatment technology of colloidal gold products can be used for reference in the coupling of quantum dot microspheres, but the freezing of quantum dot microspheres in solution state or long-term preservation below 2 ℃ should be avoided as far as possible in the experimental process. this will destroy the surface structure of quantum dot microspheres.
The structure of quantum dot microspheres contains a very thick protective layer, which is much more stable than conventional quantum dots. There is no fluorescence attenuation in all kinds of conventional medical, food and drug testing samples, and customers do not have to worry about fluorescence attenuation at all. This is extremely conducive to the development of follow-up products.
In the normal storage process, especially during long-term static storage, it may be observed that quantum dot microspheres precipitate at the bottom of the tube, but this does not affect the use of Beredin quantum dot microspheres. We recommend 60-120w ultrasonic 3min before use. If the coupled QDs microspheres precipitate after storage, we suggest that the coupled QDs microspheres be used after 60-120w ultrasonic 1min.
There are about 200,300 functional groups on the surface of each single-core quantum dot microsphere, and each microsphere contains about 500-1000 functional groups. Due to the space hindrance and selection point, not every functional group can play around, and this data is only for interested customers' reference.
It is the most stable in the range of pH6.0-9.6, and it is not recommended to be lower than PH5.5, which may lead to irreversible self-aggregation of quantum dot QDC-2.
The artificial serum is transported in an ice bag. After receiving the artificial serum, if it needs to be used in batches, it can be sub-packed, and then the artificial serum can be stored at-20 degrees.
