sentence: Of note , the investigated IGSC 20 % is stabilized with glycine and has an osmolality within the physiological plasma range ; these factors may contribute to its high degree of tolerability compared to immunoglobulin products for subcutaneous administration using other stabilizers and / or with an osmolality outside of the physiological range 37 , 38 The high concentration of IGSC 20 % resulted in smaller infusion volumes and the favourable tolerability profile enabled the infusion of comparatively large volumes per site at high rates .
