Lso developed a method for preparing SAimmobilized redoxsensitive nanohydrogels by means of peptide taginduced disulfide VU0361737 site formation mediated by horseradish peroxidase (HRP) (Fig. a) . In this system, the peptides with sequences of HHHHHHC (Ctag) and GGGGY (Ytag) have been genetically fused to the N and Ctermini of SA (CSAY), respectively. Here, H, C, G and Y denote histidine, cystein, glycine and tyrosine, respectively. The CSAY was mixed with HRP and thiolfunctionalized arm PEG to yield a CSAYimmobilized hydrogel (CSAY gel) crosslinked with redoxsensitive disulfide bonds. The CSAY immobilized in the hydrogel retained its affinity for biotin, allowing the incorporation of any biotinylated functional biomolecules or synthetic chemicalFig. Schematic illustration of photolytic PAggs formation and lightinduced release of active proteins. a The chemical GS 6615 hydrochloride site structure of BCR consisting of a biotinylated photocleavable protection group (red) and an aminoreactive group (black). b Schemes of PAggs formation. c Protein photoliberation from PAggs (Figure reproduced with permission fromRef Copyright with permission from John Wiley and Sons)Nagamune Nano Convergence :Web page of.
