PARTICLES CONTAINING DETECTABLE ELEMENTAL CODE

摘要

The invention relates to a new type of element encoded particles suitable for the attachment of bio molecules to enable massively multiplex bio-analytical methods, and to calibrate and tune the elemental flow cytometer mass spectrometer (FC-MS) (FIG. 1).

主权项

1. A first element encoded particle for use in elemental analysis with an elemental analyzer, the first element encoded particle comprising: a unique combination of at least two staining elements, the at least two staining elements and the unique combination of the at least two staining elements selected such that, upon elemental analysis by the elemental analyzer, a distinct signal is obtained from the combination of the at least two staining elements, wherein the distinct signal obtained from the combination of the two staining elements serve as a signature of the first element encoded particle that distinguishes the first element encoded particle from element encoded particles stained with a different staining element or a different ratio of the at least two staining elements.
