Click-Chemistry Reagent for Mass Cytometry
Click-chemistry mediated labeling of target molecules
This technology is a novel mass cytometry compatible molecular probe that uses click-chemistry mediated labeling of target molecules. This new lanthanide(Ln)-chelated azide containing probe allows for the detection of an expanded range of molecular features by mass cytometry compared to lanthanide-tagged antibodies.This probe is not dependent on antibodies and can be used with multiple lanthanide tags. Its flexibility allows simultaneous, multi-parametric detection of molecular targets via antibodies with RNA synthesis, lipid regulation of proteins and other emerging mass cytometry applications.
Potential applications of this technology include high precision identification of populations of immune cells, simultaneous characterization of drug responses in multiple cell types, dynamics of cell differentiation, and DNA synthesis.
Expanded range of molecular targets
Flow cytometry, the current method of choice for detecting molecular targets, can only detect 20 or fewer molecular targets and requires complex mathematical calculations for deconvolution of the data. Mass cytometry, which uses lanthanide-tagged antibodies to detect molecular targets in individual cells, is best suited for detecting proteins but not other types of molecular features. Until now, no click-chemistry reagent containing lanthanide-tagged probe has been available. This new technology offers a more versatile strategy that allows labeling with a lanthanide ion of choice. It shows results comparable to current antibody-based methods. The novel Ln-azide probe can be loaded with multiple lanthanide tags for multiparametric assays.
