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

Photo-reactive poly(vinyl alcohol) (PRPVA) was synthesized by introduction of phenyl azido groups into poly(vinyl alcohol) (PVA) and applied for surface modification. PRPVA was grafted onto cell culture plate surface homogeneously or in a micropattern. Human mesenchymal stem cells (hMSCs) cultured

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

Chitosan (CS) was covalently immobilized onto polylactic acid (PLA) film surface using the photosensitive hetero-bifunctional crosslinking reagent, 4-azidobenzoic acid, which was previously bonded to chitosan by reaction between an acid group of the crosslinking reagent and a free amino group
