Hydrogels derived from synthetic polymers have been previously engineered to degrade under the activity of matrix metalloproteinases (MMPs). It is believed that these systems can act as extracellular-matrix (ECM) equivalents mimicking the degradation and remodeling of the ECM through the

A novel chemical conjugate between chitosan (CH) and riboflavin (RF) has been synthesized and characterized via Fourier transform infrared, NMR, and other spectroscopic methods. Photophysical and photochemical properties such as absorption spectra, fluorescence emission, fluorescence anisotropy, and singlet oxygen generation

Bis(maleidophenyl)-PEG2000 (Bis-Mal-PEG2000), a new bifunctional protein cross-linker targeted to sulfhydryl groups, introduces intra-tetrameric cross-links into oxy-HbA in nearly quantitative yields. Structural as well as crystallographic analyses of the cross-linked species, Bis-Mal-PEG2000 HbA, identified Cys-93(beta) as the site of intramolecular cross-linking.

High-density poly(ethylene glycol) (PEG) molecules are grafted onto Si surfaces in a brush-like configuration. We demonstrate that this surface is an excellent substrate for oligonucleotide immobilization. p-Maleimidophenyl isocyanate is used as a heterobifunctional cross-linker to tether thiol-modified oligonucleotides to terminal
M E Annunziato et al.
Bioconjugate chemistry, 4(3), 212-218 (1993-05-01)
p-Maleimidophenyl isocyanate (PMPI, 1) is a heterobifunctional cross-linking agent useful for thiol to hydroxyl coupling. Several maleimide-activated compounds were prepared and characterized and then shown to be reactive with thiol-containing proteins. Examples include activation of vitamin B12, digoxigenin, digitoxigenin, estradiol
