abstract = {Superparamagnetic nanoparticles have recently gained much
attention due to their broad range of applicability
including medical in vivo technologies, sensors and as
supports for catalysts. As magnetic affinity materials, they
can be utilized for the development of new purification
strategies for pharmaceuticals and other target molecules
from crude lysates. Here, a short peptide tag based on a
glutamate sequence is introduced and the adsorption of pure
protein as well as protein from crude cell lysate at
different conditions is demonstrated. Fused to a model
protein this tag can be used to recognize and purify this
protein from a fermentation broth by bare iron oxide
nanoparticles (BIONs). Binding of up to 0.2 g protein per g
nanoparticles can be achieved and recovered easily by
switching to a citrate buffered system. For a deeper
understanding of the separation process, the aggregation and
agglomeration of the nanoparticle protein systems were
monitored for binding and elution steps. Furthermore, an
upscaling of the process to the liter scale and the
separation of a green fluorescent protein (GFP) containing
the affinity tag to purities of $70\%$ from E. coli
fermentation broth was possible in a one step process by
means of high gradient magnetic separation (HGMS).},
