Cat. No.: HY-Y0623
CAS No.: 6066-82-6
Synonyms: HOSu; 1-Hydroxy-2,5-pyrrolidinedione
N-Hydroxysuccinimide (HOSu; 1-Hydroxy-2,5-pyrrolidinedione) is a covalent crosslinker commonly used in bioconjugation technology with a primary amine group. N-Hydroxysuccinimide reacts with amino groups (-NH2) to form a stable amide bond, which can modify amino-containing biomolecules. N-Hydroxysuccinimide can be used, for example, for protein labeling with fluorescent dyes and enzymes, surface activation of chromatography supports, microbeads, nanoparticles and microarray slides, and chemical synthesis of peptides. N-Hydroxysuccinimide has a wide range of applications in biomaterial synthesis (such as collagen, chitosan crosslinking), drug delivery systems (such as hydrogel preparation) and tissue engineering .

Fmoc-His(Trt)-OH is a histidine derivative with a trityl (Trt) group protecting the His side chain. Fmoc-His(Trt)-OH also has an Fmoc group protecting the α-NH2 group. Fmoc-His(Trt)-OH can be used in solid-phase peptide synthesis to prevent racemization and byproduct formation. Fmoc-His(Trt)-OH acts as a protected histidine precursor in solid-phase peptide synthesis (SPPS), participating in peptide chain construction through amide bond formation. Fmoc-His(Trt)-OH can be precisely incorporated into the target peptide sequence, ensuring correct peptide chain synthesis and reducing impurity formation. Fmoc-His(Trt)-OH is mainly used in the solid-phase synthesis research of pharmaceutical peptides and bioactive peptides, and is particularly suitable for the preparation of peptide drugs requiring precise control of histidine configuration .

Synonyms: Dextran 3; Dextran D3; Dextran T3(MW 2400-3600)
Dextran T3 (Dextran 3; Dextran T3(MW 2400-3600)) is a neural tracer and intestinal permeability probe that can move anterogradely and retrogradely in neuronal axons by passive diffusion. Dextran T3 (MW 3,000) is able to permeate across the intestinal epithelial cell membrane in the presence of cholera toxin-induced cytoskeletal disturbance. Dextran T3 (MW 3,000) is used as a fluorescent marker to rapidly label developing neurons (such as Xenopus retinal ganglion cells) and to assess intestinal barrier function. It can be used to study axonal transport in neuroanatomy and permeability changes in intestinal pathophysiology. The Dextran series of compounds are also natural polysaccharide drug carriers that can be connected to drugs through covalent bonding methods such as ester bonds, amide bonds or click chemistry, or self-assembled to form carriers such as nanoparticles and hydrogels. Dextran is biodegradable and biocompatible, and can achieve targeted delivery and controlled release of drugs. Dextran derivatives can prolong the half-life of drugs, increase local concentrations, and reduce the activity of immune clearance .
