Dimethyl-3,3'-dithiobispropionimidate penetrates intact human erythrocytes and cross-links many of the membrane proteins to hemoglobin as well as to each other. The cross-linked complexes so produced have been analyzed by both one- and two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis, making

A cleavable cross-linking reagent, dimethyl-3,3'-dithiobispropionimidate, was used to study the molecular organization of adrenocortical cytochrome P-450scc. Extensive cross-linking was found to occur, resulting in the formation of heterologous oligomers up to octamer. The covalently cross-linked complex of adrenocortical cytochrome P-450scc

A single nuclear protein (Myc-associated protein) can be specifically cross-linked to avian Myc proteins by treatment of nuclei or cells with the reversible cross-linker dimethyl 3,3'-dithiobis-propionimidate. Myc-associated protein has a molecular weight of approximately 500,000, is not detectably phosphorylated and

Protein-protein cross-linking was used to determine the spatial arrangement of proteins within the 60 S ribosomal subunits of Saccharomyces cerevisiae. Protein cross-links were generated by treatment of intact ribosomal subunits with dimethyl 3,3'-dithiobispropionimidate. Proteins were extracted from the treated subunits
