20230137154 · 2023-05-04 ·

A column for removal of a component from a fluid is disclosed. The column has a compartment with a cross sectional area. The compartment contains beads having a diameter. A ligand selected to bind to the component is coupled to the beads. The cross-sectional area and bead diameter are selected to maintain a flow velocity of the fluid within the compartment below a first threshold, thereby reducing leaching of the ligand into the fluid. Also described herein is an adsorbent comprising a ligand that is attached to a substrate by an amine bond, wherein the ligand is resistant to dissociation from the substrate.

20230192768 · 2023-06-22 ·

Peptide with high binding affinity for tumor necrosis factor alpha (TNF-α). The peptide has an amino acid sequence of SEQ.ID.NO.1, or the peptide is a tandem or branched peptide with a single repeat or multiple repeats of SEQ.ID.NO.1 and SEQ.ID.NO.3 and has an amino acid sequence of SEQ.ID.NO.4. The peptide can bind to TNF-α with high affinity and can antagonize TNF-α function. When being directly injected to an animal, the peptide can significantly reduce the degree of inflammation of an animal body and improve the resistance of the animal body on an inflammatory damage. The peptide can be used for developing TNF-α antagonist drugs for treating various acute and chronic inflammatory damage, such as inflammatory, autoimmune and stress damage caused by physical, chemical and biological factors. Thus, the peptide has an extremely wide application prospect. Moreover, the peptide has a small molecular weight and low immunogenicity, and is easy to synthesize, thereby avoiding the side effects and disadvantages of traditional monoclonal antibody drug antagonists.
