Features and Benefits

Fmoc-N-amido-dPEG2-acid is a monodisperse PEG product that is useful for peptide synthesis. The ten-atom dPEG spacer allows the introduction of a short, hydrophilic spacer onto either end of a peptide chain or between two peptide chains. The flexible dPEG spacer conjugates to peptides using conventional peptide synthesis chemistry. Peptide PEGylation imparts water solubility to hydrophobic peptide chains. Also, PEGylated peptides have expanded hydrodynamic volumes, which can reduce or eliminate renal clearance, and are protected from proteolysis. The combination of decreased renal clearance and protection from proteolysis contributes to longer in vivo circulation times for PEGylated (as compared to non-PEGylated) peptides. Additionally, PEGylation diminishes a peptide′s antigenicity. This product is part of the Fmoc-N-amido-dPEGn-acid (n=2, 3, 4, 5, 6, 8, 12, 24, 36) product series.

We report a general procedure to prepare functional organic thin films for biological assays on oxide surfaces. Silica surfaces were functionalized by self-assembly of an amine-terminated silane film using both vapor- and solution-phase deposition of 3'-aminopropylmethyldiethoxysilane (APMDES). We found that

The high incidence of BB2 receptor (BB2r) expression in various cancers has prompted investigators to pursue the development of BB2r-targeted agents for diagnostic imaging, chemotherapy, and radiotherapy. Development of BB2r-targeted agents, based on the bombesin (BBN) peptide, has largely involved

The remarkable diversity of the self-assembly behavior of PEG-peptides is reviewed, including self-assemblies formed by PEG-peptides with β-sheet and α-helical (coiled-coil) peptide sequences. The modes of self-assembly in solution and in the solid state are discussed. Additionally, applications in bionanotechnology

Ligand-targeted nanoparticles are emerging drug delivery vehicles for cancer therapy. Here, we demonstrate that the cellular uptake of peptide-targeted liposomes and micelles can be significantly enhanced by increasing the hydrophilicity of the targeting peptide sequence while simultaneously optimizing the EG
