The invention provides an aqueous formulation comprising water and a protein, and methods of making the same. The aqueous formulation of the invention may be a high protein formulation and/or may have low levels of conductity resulting from the low levels of ionic excipients. Also included in the invention are formulations comprising water and proteins having low osmolality.本發明係提供包含水與蛋白質之含水調配物,及其製造方法。本發明之含水調配物可為高蛋白質調配物,及/或可具有由於低含量離子性賦形劑所造成之低程度導電率。亦被包含在本發明中者為包含水與具有低滲透度蛋白質之調配物。
