Expedeon AG has announced that it has introduced Lightning-Link(R) Metal Labelling Kits for use in multiple immunoassay-based applications to support single cell analysis. The new kits will enable users to dramatically enhance the phenotypic analysis of heterogeneous cell populations, providing increased multiplexing capability compared to fluorophore labelling, improving sample throughput and research output. Metal labelling is a technique using rare metal isotopes as opposed to fluorophores for antibody labelling, distinctly increasing the available analytical spectrum. Because the metals do not produce the background noise associated with fluorophores, multiplexing capabilities are greatly increased. This technique is utilised in numerous fields such as immunology, oncology, phospho-proteomics and haematology through its associated applications, such as dissociation-enhanced lanthanide fluorescence immunoassays, multiplexed ion beam imaging, x-ray fluorescence and mass cytometry (cytometry by time-of-flight). By using antibodies (or other probes) labelled with purified metal isotopes, mass cytometers can detect more than 50 different parameters at a single-cell level, exceeding the dimensionality of any other flow cytometry methodology currently on the market. Expedeon's metal labelling kits require just 30 seconds hands-on time, a significant improvement from the current available methods which require hours to perform, and offer clear improvements in terms of efficiency and ease of use.
