Recombinant protein aggregation is a problematic issue and can provoke immunological response. The aim of this study was to analyze the stability of erythropoietin (EPO), as a therapeutic protein expressed in mammalian cells, in the presence of different chemicals and find a specific stabilizer for EPO. The effects of several chemicals, including mannitol, betaine, trehalose, taurine, linoleic acid, beta-cyclodextrin, copper sulfate, spermidine, maltose, maltodextrin, sucrose, dextran, beta-alanine, myo-inositol, and cysteine, on protein stabilization through the thermally induced aggregation of EPO were monitored...
