polystyrene

Polystyrene microplastics (PS-MPs) are a toxic substance that poses risks to aquatic life, specifically causing cardiac harm to zebrafish and inducing male reproductive toxicity in mice [1] [2].

Filastatin is a durable inhibitor of Candida albicans filamentation and exhibits potent antifungal activity.

Calcium polystyrene sulfonate (Poly(styrenesulfonic acid) calcium salt) is an ion-exchange resin. Calcium polystyrene sulfonate reduces blood levels of potassium and can be used for research on the treatment of hyperkalemia in patients with chronic kidney disease.

5,10,15,20-Tetrakis(4-methoxyphenyl)porphyrin is a porphyrin derivative capable of forming complexes with metal ions such as zinc (Zn), copper (Cu), and cadmium (Cd). These metal complexes exhibit phototoxicity towards Hep-2 cells, causing cell inactivation through the generation of singlet oxygen.

1. Ginkgolic acid C17:1 can significantly inhibit enterohemorrhagic Escherichia coli O157:H7(EHEC) biofilm formation on the surfaces of polystyrene and glass, and on nylon membranes.

Poly(styrenyl acetal trehalose) (pSAT) is synthesized by linking trehalose side chains to a polystyrene backbone through acetal bonds. This compound stabilizes various proteins and enzymes against temperature fluctuations without triggering an innate immune response. Additionally, Poly(styrenyl acetal trehalose) can be utilized in synthesizing protein-polymer conjugates, thereby reducing the renal clearance of active molecules.

AEX Anion-exchange resin 1 is a strong anion exchange chromatographic medium with a monodisperse polystyrene/divinylbenzene (PS-DVB) matrix and a particle size of 50 μm, featuring an ion exchange group of –CH2N+(CH3)3. It is suitable for the separation and purification of biological macromolecules such as proteins, antibodies, and viral vaccines.

CEX Cation-exchange resin 1 is a cation-exchange chromatography medium, based on monodisperse polystyrene/divinylbenzene (PS-DVB). With a particle size of 50 μm, its functional group is -CH2CH2CH2SO3-. CEX Cation-exchange resin 1 is suitable for the separation and purification of antibodies, VLPs, viruses, and proteins.
