NS indicates not significant; IDDM, insulin-dependent diabetes mellitus; and EAE, experimental autoimmune encephalitis.
As stated by the manufacturer.
Based on isotype.
Based on the present study at a dose of 50 μg/mouse.
All recognize epitopes in the hyaluronan-binding region.
Recognize a different epitope than KM114 and KM201 (as stated by the antibody data sheets of BD Biosciences PharMingen).
