The aggregation of hOPG decreases with the addition of additives. Particle size distribution determined by DLS analysis of hOPG purified (a) in the absence of additives (% cumulative polydispersity index = 0.32) and (b) in the presence of 0.1 M L-arginine and L-glutamic acid, 0.2 M trehalose and 2 mM DTT (% cumulative polydispersity index = 0.10). |
