Xdrop and Xdrop Sort offer a unique format for rapid, highly accurate functional analyses of mammalian and microbial cells as well as for highly targeted sequencing of DNA, including edited genes.
Xdrop and Xdrop Sort ensure:
What could you achieve if you boosted the speed and accuracy of your functional analyses of living cells? Find out with our benchtop instruments, Xdrop and Xdrop Sort.
Both instruments encapsulate living cells in highly stable double-emulsion droplets that act as picoliter-sized microenvironments for incubation and downstream analyses.
They change how you analyze cells by transforming bulk functional analyses and bulk screening into rapid and accurate assays with a unique single-cell format.

Xdrop and Xdrop Sort produce double-emulsion droplets that act as picoliter-sized reaction chambers or microenvironments for your cells, allowing you to:
Xdrop has proven performance in a range of single-cell format applications, including:
Both Xdrop and Xdrop Sort have proven performance with microbial cells, including

Xdrop generates two sizes of double-emulsion droplets: DE20 and DE50. The Xdrop DE20 Cartridge generates DE20 droplets, which are ~20 µm in diameter (volume: ~1.6 picoliters) and are suitable for microbial cell workflows. The Xdrop DE50 Cartridge generates DE50 droplets, which are ~50 µm in diameter (volume: ~100 picoliters) and are suitable for mammalian cell workflows. Xdrop Sort generates DE20 droplets and can also sort them based on fluorescence signals.

Xdrop DE20 and DE50 droplets encapsulate cells along with their growth medium. Small molecules, such as carbon dioxide and water, can diffuse across the double-emulsion shell. However, large, complex molecules, such as cytokines, remain inside the droplet.
This means:
Essentially, cells can happily stay in DE20 or DE50 droplets for the duration of your experiments!
Validating CRISPR edits and identifying CAR cassette insertions are essential to cell and gene therapy research. Xdrop and Xdrop Sort have protocols that support highly targeted long-read and short-read sequencing of DNA. The workflow involves encapsulating DNA for targeted enrichment in double-emulsion droplets, then sorting to capture the region of interest. Downstream sequencing reveals unintended on-target and off-target rearrangements that other methods cannot easily find.
