Modified Microspheres
Microsphere Modifications
Capture Reagents: Our microsphere modification services are customized to your needs. You can choose the volume, the xMAP microsphere designation, and the capture reagent. We are not limited to single source reagent manufacturers, so we will bulk couple the reagent of your choice, without regard to its original source.
Alternative Functionalities: We also provide various chemical modifications that give you even more options for assay development and optimization. We have developed several alternative surface chemistries that can be used for more specific research needs. The choice of chemical modification depends on the functionality of your capture reagent. The following table classifies the capture reagents that can be used for different assay formats.
