DMSO affects the efficiency of photolabeling of tetrabrominated rhodamine to collagen fibers

摘要

The ability to photolabel a compound, tetrabrominated rhodamine (TBR), onto collagen gels was tested. The influence of DMSO on the efficiency of photolabeling was determined. The DMSO enhances the photolabeling presumably by allowing the TBR to become more closely associated to the collagen fibers such that upon photon absorption which causes debromination to yield a radical, the radical can covalently link to the collagen.
