Abstract
A high throughput device is provided for simultaneously isolating periplasmic fractions from multiple samples of host cells. The device can be formatted to operate in a series. A method for simultaneously isolating multiple periplasmic fractions is also provided. The method includes (a) providing a high throughput device for isolating periplasmic fractions from multiple samples of host cells having an outer membrane via attaching a removable sample chamber having a membrane chamber wall to a vacuum chamber and applying a vacuum thereto (b) removing media with the vacuum and (c) removing the outer membrane of the host cells (d) attaching a collection chamber to the vacuum chamber and applying a vacuum thereto in order to carry out a collection of the periplasmic fractions that pass through the membrane of the chamber wall from the host cells. A workstation is also provided which includes one or more high throughput devices for simultaneously isolating periplasmic space fractions from a plurality of samples of host cells, and a device for simultaneously culturing a plurality of samples. preferably the membrane of the chamber is a neutral nylon membrane having an average pore diameter…
