Disulfide Cross -Linking in Protein Microspheres
… that disulfide bonds are the covalent cross-link between protein molecules. Mass spectrometry has shown that inter-protein disulfide bonding is not random. The disulfide bonds that do form reflect the electrostatic surfaces of the proteins as they approach each other during …

Regulation of Human Monocyte Function by Cross-Linking of Immunoglobulin E
Cross-linking of IgE by allergen triggers many cellular processes that drive allergic disease. While the role of IgE in mediating allergic responses is best described on basophils and mast cells, expression of the high-affinity IgE receptor on other innate immune cells, including monocytes, …

The cross-linking mechanism of filamin A in the actin cytoskeleton
… abundant actin-binding protein that efficiently cross-links actin filaments in large-angle orientations, requiring the lowest concentration to convert actin filaments into a cohesive gel. Filamin dimers are composed of two 24-repeat domains that come together like a V with an actin-binding region …

KINETICS OF POLYMER CYCLIZATION REACTION AND NOVEL COVALENT DNA CROSS-LINKING ASSAYS
In this dissertation I first do an extensive review of polymer cyclization kinetics. Different theories of polymer cyclization kinetics, their assumptions and their predictions are presented along with the predictions of computer simulations. In addition, the experimental results for synthetic and …

Characterisation of the cross-linking and calcification associated with glutaraldehyde-treated cardic bioprostheses.
… valves for the last thirty years, as a cross-linking agent and a sterilant. Whilst it is assumed to introduce stable inter- and intra-fibrillar collagen cross-links, which contribute to the durability of these valves, the specific chemistry of the fixation process is not fully …

Synthesis and biological evaluation of potential DNA cross-linking agents based on pyrrolizidine alkaloids
DNA cross-linking agents represent one of the most potent categories of antitumor agents. Pyrrolizidine alkaloids are an abundant class of biologically active natural products. These alkaloids display high levels of DNA cross-linking ability, and could have potential use as antitumor agents. …

Basic studies of the cross-linking reaction of collagen with oxazolidine and plant polyphenols
… and gallocatechin, it was shown that the cross-linking reaction of gallocatechins can happen between an A- ring and a B-ring, while for catechin, the reaction is only at the A-ring. Polyphenol polymer studies also support this result; more oxazolidine can be reacted with prodeiphinidins. …

Large Scale Cross-Linking Mass Spectrometry as the Missing Link in the Systems Biology Toolbox
… sufficient detail, and in a generalisable way. Cross-linking mass spectrometry (XL-MS) performed on high complexity samples (such as entire organelles or cells) theoretically enables the large scale mapping and monitoring of protein structural conformations and PPI interfaces in native …

NOVEL G-QUADRUPLEX BINDERS WITH POTENTIAL FOR A DUAL DNA CROSS-LINKING MECHANISM OF ACTION
… residues and could potentially result in the cross-linkage of DNA strands, preventing uncoiling of the DNA double helix leading to cell death. More recent evidence show that guanine-rich nucleic acids can fold into distinctive four-stranded conformers found in telomeric DNA repeats (i.e. …

Synthesis and Evaluation of Trans-bilayer Cross Linking Phospholipids Based on Click (Azide-Alkyne) Chemistry
This thesis describes the synthesis of two phosphatidylcholine (PC) derivatives that are capable of coupling with each other from the alkyl chain through click reaction to form bola-PC. Successful coupling of monomeric phosphatidylcholine derivatives would lead to synthesis of corresponding …
