Quantum dots microspheres are mainly used in quantitative lateral flow assays to achieve increased sensitivity. Its long Stokes shift, photostability and high quantum yield of fluorescence make it possible to overcome the limitations encountered by conventional organic fluorophores.
* Custom pack size is available upon the request of customers.
Our quantum dots microspheres offer several advantages, such as:
1、 Superior optical properties in beads based multiplex lateral flow assay.
2、 One step antibody coupling procedure.
3、 Easy centrifugation steps (500g for 5 min) to shorten production time.
Stability and storage, 24 months shelf life at 2-8°C.
Dispersing Agents
This product is supplied as a 10x solution containing dispersing agents. It can be added to sample dilution buffer or sample pad to reduce endogenous interference caused by lipoproteins or fibrin in blood samples. This, in turn, improves the mobility of microspheres through the lateral flow membrane.

Microspheres
Despite the wide use of colloidal gold as an effective carrier in lateral flow tests, its sensitivity in certain assays remains limited. Gold shell microspheres are characterized by a core-shell structure with particle sizes ranging from 280nm to 320nm. T
