Biotium has announced the release of the ViaPlex 2-Color Cell Barcoding Kit. Combining fluorescent staining with two reactive dyes, the ViaPlex kit allows researchers to label and combine up to 15 distinct cell populations for multiplex analysis in a single tube, reducing reagent consumption and sample running time without compromising data quality. After barcoding with the ViaPlex Cell Barcoding Kit, labelled cell populations can be combined into a single tube for antibody staining and later distinguished during flow cytometry analysis. Biotium’s new kit contains two cell-permeant reactive fluorescent dyes, ViaPlex 405 Barcoding Dye for the 405 nm laser/Pacific Blue filter, and ViaPlex 488 Barcoding Dye for the 488 nm laser/FITC filter, used at different concentrations to generate a 15-plex barcoding matrix, with an optional 16th sample possible with compensation. The ViaPlex Cell Barcoding Kit expands Biotium’s portfolio of high-performance reagents for flow cytometry, providing researchers with a convenient and cost-effective solution for multiplex sample analysis and high-throughput experimental workflows.
