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

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

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

Atomic force microscopy (AFM) experiments with functionalized tips are currently one of the most powerful tools to locally measure adhesion forces via single-molecule force spectroscopy (SMFS) measurements. The main difficulty is to precisely control the attachment of biomolecules to the
