biopolymer

Lignin (Lignine), the primary component of plant cell walls, is a renewable aromatic polymer with strong antioxidant activity. This natural complex biopolymer is both biodegradable and biocompatible.

Kefiran is a microbial biopolymer able to form gels. It also has the advantage of displaying antimicrobial activity.

Diazoluminolmelanin is a synthetic luminescent biopolymer.

Silk fibroin, suitable for cell culture, is a widely used natural biopolymer ideal for cell culture. [Silk fibroin] serves as a scaffold material that meets specific requirements for biocompatibility, biodegradability, and tissue specificity.

Dextran sulfate, low sulfate (MW 5000), is a natural biopolymer and a sulfated polysaccharide. It exhibits antiviral, antibacterial, anti-inflammatory, antifibrotic, and wound healing properties. Additionally, dextran sulfate serves as an additive in cell culture media to prevent cell aggregation and functions as a gel-forming agent in cosmetics.

Dextran sulfate, low sulfate (MW 40000) is a sulfated polysaccharide biopolymer. It exhibits antiviral, antibacterial, anti-inflammatory, antifibrotic, and wound healing properties. Additionally, dextran sulfate can be employed as an additive in cell culture media to prevent cell clumping and as a gelling agent in cosmetic formulations.

Dextran sulfate, high sulfate (MW 5000), is a sulfated polysaccharide that functions as a biopolymer. It exhibits antiviral, antibacterial, anti-inflammatory, antifibrotic, and wound-healing properties. Additionally, dextran sulfate can be utilized as an additive in cell culture media to prevent cell aggregation and serves as a gelling agent in cosmetics.

Poly-L-Glutamic acid (MW 100000) is a biopolymer composed of L-glutamic acid units that exhibits activity in forming stable, water-soluble complexes with metal ions and is extensively used in the production of biodegradable materials.

TCO-PEG4-TFP ester is an amine-reactive labeling reagent used for the modification of proteins, antibodies, and other amine-containing biopolymers. TFP is a reactive ester that demonstrates superior stability during hydrolysis in aqueous media, enhancing the efficiency and reproducibility of biopolymer labeling. The TFP ester of carboxylic acid reacts with primary amines at a rate equivalent to NHS esters, forming a covalent amide bond identical to that produced by the reaction of primary amines with NHS or sulfo-NHS esters.
