Abstract:
1. A method of measuring a molecular weight of hyaluronic acid, comprising at least the following steps (1) to (3): (1) measuring a concentration of hyaluronic acid in a sample; (2) reacting hyaluronic acid in a sample containing the hyaluronic acid with a hyaluronic acid-binding protein, and measuring an amount of the hyaluronic acid-binding protein that is bound to the hyaluronic acid in the sample or a value that reflects the amount; and (3) determining the molecular weight of the hyaluronic acid in the sample from the concentration of the hyaluronic acid in the sample obtained in step (1); and the amount of the hyaluronic acid-binding protein that is bound to the hyaluronic acid in the sample or the value that reflects the amount obtained in step (2),
