Culture supernatants fibre device

If a low-secreting cell line is the best available and the antibody is important, the only option is to grow a large quantity of cells and to concentrate the culture supernatant before further processing. These objectives can both be accomplished in a hollow fibre fermenter. Alternatively, supernatant from conventional cultures can be concentrated in a variety of devices. Hollow fibre kidney dialysis cartridges are particularly convenient, being reliable, free from endotoxin, easy to use, and cheap.
