To study the interaction of the TCR with its ligand, the complex of a MHC molecule and an antigenic peptide, we modified a TCR contact residue of a H-2Kd-restricted antigenic peptide with photoreactive 4-azidobenzoic acid. The photoreactive group was a
Photoreactive pullulan was prepared, the polymer was photoimmobilized on polymeric or organic surfaces, and its interactions with a protein and a cell type were investigated. The photoreactive pullulan was synthesized by a coupling reaction with 4-azidobenzonic acid. Surface modification was
Restoring continuity to severed peripheral nerves is crucial to regeneration and enables functional recovery. However, the two most common agents for coaptation, sutures and fibrin glues, have drawbacks such as inflammation, pathogenesis, and dehiscence. Chitosan-based adhesives are a promising alternative

Hydroxypropyl chitosan (HPCS), a water-soluble chitosan derivate, was modified by introducing photoreactive azide groups (4-azidobenzoic acid, Az-) to the amino groups of HPCS, resulting in a photocrosslinkable Az-HPCS. Novel porous chitosan scaffolds thus were fabricated by ultraviolet (UV) light irradiation

Here, the surface of silicone elastomer was modified with photo-reactive gelatin bearing azidophenyl groups. Two types of gelatin were prepared: one by coupling with azidoaniline and the other by coupling with azidobenzoic acid. The silicone surface was hydrolyzed by oxygen
