In a study of the action of thrombin on fibrinogen and a comparison of this enzyme with trypsin, several fibrinogen-like oligopeptides were synthesized. The hydrolysis of the arginyl-glycine bond in these peptides, by both of these enzymes, is examined and compared.
Biodegradable oligolysine and oligoarginine-type homopeptides functionalized with PEG of two different molecular weights interact with insulin, at physiological pH, affording complexes studied by dynamic light scattering, ζ-potential, circular dichroism, FTIR spectroscopy, and isothermal titration calorimetry (ITC). High levels of insulin complexation efficiencies (>99.5%) were determined for a...
In order to study the interaction of cysteine containing peptide chains with Hg(II) the nuclear quadrupole interaction (NQI) of 1 9 9 m Hg in the Hg complex of the oligopeptide Alanine-AlanineCysteine-Alanine-Alanine (AACAA) was determined by time differential perturbed angular correlation. Different 1 9 9 m H g N Q I ' s for free and resin-bound A A C A A were obtained. Furthermore, the 1 9 9 ...
In this review, we describe different methods of microarray fabrication based on the use of micro-particles/-beads and point out future tendencies in the development of particle-based arrays. First, we consider oligonucleotide bead arrays, where each bead is a carrier of one specific sequence of oligonucleotides. This bead-based array approach, appearing in the late 1990s, enabled high-throughp...
We prepared the bioactive liquid crystal (LC) droplets by decorating an oligopeptide at the LC/aqueous interface to stabilize the LC droplets. These LC droplets can be used to detect proteases through the specific cleavage of protease on an oligopeptide leading to a bipolar-to-radial transition of LC configuration inside the droplets.
