8 Interaction analysis study signal transduction pathways using crosslinkers to trap, isolate and identify interactions between proteins, membrane receptors and nucleic acids Conjugation create custom conjugates by covalently linking biomolecules, eg: proteins, nucleic acids, drugs, peptides, hormones metabolites and cellular organelles. Immobilization - immobilize antibodies and other proteins, nucleic acids or cells to resin, the extracellular matrix, chips, slides or nanoparticles. In vivo crosslinking trap protein complexes in live cells by treating cells with membrane permeable crosslinking reagents. Labeling tag proteins or nucleic acids with various reporters, such as fluorophores. Structural analysis study proteins oligomerization or the formation of heterologous protein complexes by mapping binding sites. Antigen preparation crosslink antigens to carrier proteins for animal immunization/antibody produciton. Protein alkylation chemically block amino acid functional groups on proteins. Amine-to-Amine Sulfhydryl-to-Carbohydrate Sulfhydryl-to-Sulfhydryl Photoreactive Amine-to-Sulfhydryl Chemoselective Ligation Membrane Permeable Carboxyl-to-Amine (click chemistry metabolic labeling) (In vivo crosslinking)
