Abstract

Monoclonal antibodies are one of the most important products of biotechnology and laboratories and companies all over the world are pursuing their large-scale production. Herein we report a protocol for hybridoma cell cultivation over small glass cylinders inside a 3 liter bioreactor vessel which leads to the production and purification--in order of grams--of one MAb intended for human therapeutic use. This protocol proved to be simple, reproducible and cost effective. Three trials are reported: the first two using conventionally serum-supplemented medium culture and producing 3.15 and 2.1 g of purified MAb in 30 and 21 days respectively, and the third one using serum-free medium culture and producing 6 g of purified MAb in 36 days. We have ascertained the stability of the hybridoma by its cloning directly in serum-free medium. The downstream processing of the serum-free trial was done in a single step, concentrating large volumes of supernatant while simultaneously purifying the antibody.
