What is the fine-grained topic of the following text: It seems that my protein (size about 54 kDa) is co-purified with chaperone protein (probably GroEL - as the band is around 57kDa).... Tandem affinity purification is a development of existing techniques for purifying protein complexes from cells in physiological conditions. Only return the topic.
