Abstract

The invention discloses a composition and a preparation method and a use thereof. The composition contains protein or polypeptide and oligomerization hyaluronic acid (oligomerization HA) or salt of the oligomerization hyaluronic acid; and when being in a liquid form, the protein or polypeptide is 0.1-100 [mu]g / ml, and the oligomerization hyaluronic acid or the salt of the oligomerization hyaluronic acid is 1-20%.

Description

technical field [0001] The present invention relates to the field of biochemistry, in particular to a protein or polypeptide composition and its preparation method and application. Background technique [0002] In 1934, Meyer et al. extracted and isolated a macromolecular polysaccharide from the vitreous humor of the bull's eye, and named it hyaluronic acid. Hyaluronic acid (hyaluronan, HA) is a macromolecular linear glycosaminoglycan (GAG), which consists of repeating disaccharide units, namely D-glucuronic acid (β1-3) and N-acetyl-D- Glucosamine (β1-4). HA is widely present in organisms and has a variety of biological activities. It serves as the mechanical support of cells in many tissues such as skin, tendon, muscle and cartilage. It is the main component of the intercellular matrix and plays an important role in the moistening and lubrication of tissues. effect. [0003] HA and the respective salts have been used as medicine, especially in the treatment of joint dise...
