WebFirst, sulfhydryls are present in most proteins but are not as numerous as primary amines; thus, crosslinking via sulfhydryl groups is more selective and precise. Second, sulfhydryl groups in proteins are often involved in disulfide bonds, so crosslinking at these sites typically does not significantly modify the underlying protein structure or ... WebFormaldehyde has been used for decades to probe macromolecular structure and function and to trap complexes, cells, and tissues for further analysis. Formaldehyde crosslinking is routinely employed for detection and quantification of protein-DNA interactions, interactions between chromatin proteins, and interactions between distal segments of the chromatin …

WebJan 1, 2024 · In addition to protein labeling, covalent aptamers containing crosslinking warheads can be designed, resulting in oligonucleotide-protein conjugates. Such conjugates shield the aptamer from nuclease-meditated degradation ( Tabuchi, Yang, & Taki, 2024 ; Tivon et al., 2024 )—a known a limitation of traditional aptamers and their … WebMar 17, 2016 · General DSP Crosslinking Protocol 1.
