Abstract

The invention discloses corneal metaphase preserving liquid containing recombinant human serum albumin and a preparation method thereof. The corneal metaphase preserving liquid containing recombinanthuman serum albumin contains glutamine, calcium pantothenate, choline chloride, folic acid, inositol, nicotinamide, pyridoxal.HCl, riboflavin, thiamine.HCl, KCl, NaCl, NaH2PO4.2H2O, glucose, dextran 40, sodium pyruvate, vitamin C, chondroitin sulphate sodium, sodium hyaluronate, non-animal recombinant human serum albumin, gentamicin sulfate, sodium bicarbonate, piperazine-1-erhanesulfonic acid, phenol red indicator, and water for injection. The non-animal recombinant human serum albumin is added to replace serum to improve corneal endothelial cell survival rate; and then the non-animal recombinant human serum albumin cooperates with a compound system of the chondroitin sulphate sodium, the sodium hyaluronate and the dextran 40, the survival rate of the corneal endothelial cell is greatly ensured.

Description

technical field [0001] The invention relates to the field of corneal medium-term preservation solution containing recombinant human serum albumin, in particular to a corneal medium-term preservation solution containing recombinant human serum albumin and a preparation method thereof. Background technique [0002] Human serum albumin (HSA) is the most abundant protein in human plasma, and its main functions include: (1) maintaining the colloid osmotic pressure and pH value of the solution; (2) important components such as lipids, metal ions, amino acids and other factors body binding and transport; (3) antioxidant function. [0003] The X-ray crystal structure of human serum albumin reveals that it is a heart-shaped molecule with 585 amino acids linked in a single chain, containing 67% α-helices. The remarkable feature of the structure of human serum albumin is that there are three homologous regions (I, II and III), each region is composed of two subdomains (A-B), each heli...
