Accessible to every lab, Xdrop microfluidics products are changing how we look at cells.
Get the most precise view of the function and potency of members of your immune cell population. Quickly encapsulate millions of single living cells in microfluidics droplets that are compatible with flow cytometers, cell sorters, and incubators to get the insights you need for immune therapy research.
This droplet-based flow cytometry workflow enables simultaneous detection of granzyme B secretion and cell killing with single-cell resolution. It uses Xdrop DE50 droplets to encapsulate natural killer cells together with their targets for incubation and flow cytometry. Our findings here support the widely accepted dynamics of granzyme B secretion and cell killing, showing the utility of Xdrop in advancing our understanding of vital cell biology processes and as a powerful tool for immune cell therapy development.
In this collaboration with Agilent Technologies, we looked at the potential to rapidly identify active NK cells in a cell population. We used our Xdrop droplet-based format for an assay on the Agilent NovoCyte Quanteon flow cytometer. Target cell killing was seen within an hour of incubation, allowing the identification of the fastest killers. The assay is fast as the picoliter droplet volume leads to rapid cell–cell interactions, marking a significant advancement in the study and analysis of immune cells.
Bulk functional assays of immune cells miss highly potent cells within the population. This Xdrop single-cell format workflow for IFN-γ secretion assessment reveals these highly potent individual cells, enabling their retrieval and expansion.
Quantifying individual cells that secrete IFN-γ, TNF-α, or both cytokines in a single-cell, Xdrop®-based workflow.
This Xdrop workflow enables rapid, multiplex quantification of the individual immune cells in a population that are secreting one or more cytokines. The results for single-cell format multiplex and singleplex assay concurred and were reproducible.
Bulk functional assays of immune cells miss highly potent cells within the population. This Xdrop workflow reveals highly potent TNF-α-secreting T cells in a human blood sample.
Starting from just 10 ng of DNA, Xdrop reveals gene cassettes inserted using lentivirus and other transduction systems. Here, Xdrop reveals 1,000 unique insertion sites of the CAR cassette inserted all over the genome.
