This application provides fluidic devices, such as microfluidic devices, which can be used for the creation and/or manipulation of droplets in droplet-based microfluidic systems, as well as systems and methods for using the same. The microfluidic devices can be used to generate droplets, extract or inject volume to droplets, and/or split droplets. Also provided are methods for generating nucleosomes, and isolated DNA from nucleosomes (or from non-nucleosomes), for example using the disclosed devices.

Chromatin immunocapture devices and methods of use

In one representative embodiment, a device includes a main microchannel and at least two other microchannels. The main microchannel defines a main fluid flow path and has an opening, and first and second microchannels defining a first and second fluid flow paths, respectively. The first fluid flow path is in fluidic communication with the main fluid flow path via the opening and forms a first angle relative to the main microchannel less than 90 degrees. The second microchannel defines a second fluid flow path in fluidic communication with the main fluid flow path via the opening and in fluidic communication with the first fluid flow path. The second microchannel forms a second angle relative to the main microchannel less than 90 degrees. The first and second microchannels form a third angle relative to one another, with the third angle being between 60 and 135 degrees.
