Title:
APPLICATION OF LOW-MOLECULAR-WEIGHT HYALURONIC ACID FRAGMENTS TO INDUCE STRING AGGREGATION OF RED BLOOD CELLS
Document Type and Number:
WIPO Patent Application WO/2021/180221
Kind Code:
A1
Abstract:
Disclosed is an application of low-molecular-weight hyaluronic acid fragments to induce string aggregation of red blood cells in peripheral blood or venous blood, for use in measuring the molecular weight of low-molecular-weight hyaluronic acid fragments or measuring the molecular weight variation range of products produced between batches. The low-molecular-weight hyaluronic acid fragments having an average molecular weight of 35 kDa induce string aggregation of human red blood cells by combining CD44 on the surface of human red blood cells, for use in activity detection of the low-molecular-weight hyaluronic acid fragments. Further disclosed is that the hyaluronic acid fragments having an average molecular weight of 35 kDa have an inhibitory effect on human neutrophil activation, and can prevent and treat inflammatory diseases related to neutrophil activation and releasing various oxidation substances.
