Fig. 2From: The effects of the molecular weights of hyaluronic acid on the immune responses1 H NMR spectra of HyA with different molecular weights. The 1 H-NMR spectra was recorded using a Bruker Ascend™ 600-MHz spectrometer, where A LMW-10: low molecular weight of HyA (10 kDa), B MMW-100: medium molecular weight of HyA (100 kDa), C MMW-500: medium molecular weight of HyA (500 kDa), D HMW-1,500: high molecular weight of HyA (1,500 kDa)Back to article page
