[Novel antiproteinase hemosorbent].

Area of Science:

• Biomaterials Science
• Polymer Chemistry
• Biochemistry

Context:

• Hydrogels are widely used in biomedical applications due to their unique properties.
• Biospecific hemosorbents are crucial for targeted removal of specific molecules from blood.
• Ovomucoid, a glycoprotein from duck egg white, has potential for protein binding applications.

Purpose:

• To develop a biospecific hydrogel hemosorbent with enhanced protein absorption capacity.
• To investigate the effect of a chain transfer agent on hydrogel structure and function.
• To optimize the immobilization of ovomucoid for improved hemosorbent performance.

Summary:

• A novel method for producing a biospecific hydrogel hemosorbent was developed via radical copolymerization.
• The process involved ovomucoid derivative, acrylamide, N,N'-methylene bisacrylamide, and mercaptoacetic acid as a chain transfer agent.
• The use of mercaptoacetic acid modified hydrogel structure, increasing swelling and reducing large pores, favoring ovomucoid function.

Impact:

• The developed hemosorbent demonstrates increased absorption capacity for serine proteinases.
• Structural modifications induced by the chain transfer agent enhance the efficiency of immobilized ovomucoid.
• This advancement holds potential for improved therapeutic strategies in conditions requiring proteinase removal.
