Unlike other crosslinking agents, aldehyde-induced crosslinking is an intrinsically reversible process. NMR structure of these types of agents as interstrand crosslinks show that a 5'-GC adduct results in minor distortion to DNA, however a 5'-CG adduct destabilizes the helix and induces a bend and twist in the DNA.
Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. [1] Even if it is strongly associated with the production of thermosetting polymers , the term "curing" can be used for all the processes where a solid product is ...
BS3 binds irreversibly to its conjugate molecules, meaning that once BS3 creates covalent linkages to its target molecules, those associations are not easily broken. [ 6 ] Membrane impermeable: Since BS3 is a charged molecule, it cannot freely pass through cellular membranes which makes it an ideal crosslinker for cell surface proteins.
In polymer chemistry "cross-linking" usually refers to the use of cross-links to promote a change in the polymers' physical properties. When "crosslinking" is used in the biological field, it refers to the use of a probe to link proteins together to check for protein–protein interactions, as well as other creative cross-linking methodologies.
Cross-linking and immunoprecipitation (CLIP, or CLIP-seq) is a method used in molecular biology that combines UV crosslinking with immunoprecipitation in order to identify RNA binding sites of proteins on a transcriptome-wide scale, thereby increasing our understanding of post-transcriptional regulatory networks.
The third category involves cross-linking of enzyme aggregates or crystals, using a bifunctional reagent, to prepare carrier-free macroparticles. The use of a carrier inevitably leads to ‘dilution of activity’, owing to the introduction of a large portion of non-catalytic ballast, ranging from 90% to >99%, which results in lower space-time ...
In addition, the cross-linked protein yield is very low due to the multifunctionality of the cross-linking reagents. The process was invented (US6613582B1) in 1999 to utilize protein cross-linking techniques to analyze the interactions between polypeptides as well as structural differences proteins undergo in a catalytic pathway. The techniques ...
A distinct exothermic reaction makes a reactant "spring-loaded". The process would preferably: have simple reaction conditions; use readily available starting materials and reagents; use no solvent or use a solvent that is benign or easily removed (preferably water)
