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. Their unique surface properties and large particle size allow R&D scientist to develop rapid immunoassays with far greater sensitivity.
* Custom pack size is available upon the request of customers.
Our gold shell microspheres offer several advantages, such as:
1、 Higher sensitivity than traditional latex dyed beads.
2、 One step antibody coupling procedure.
3、 Easy centrifugation steps (500g for 5 min) to save production time and equipment costs.
Stability and storage,18 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
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 conven
