SDS of cas: 70539-42-3. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Bis(2,5-dioxopyrrolidin-1-yl) O,O’-ethane-1,2-diyl disuccinate, is researched, Molecular C18H20N2O12, CAS is 70539-42-3, about A high throughput dimer screening assay for monoclonal antibodies using chemical cross-linking and microchip electrophoresis. Author is Chen, Xiaoyu; Flynn, Gregory C..

A high throughput screening assay was developed to determine the total dimer level in antibody samples. This method utilizes high speed microchip electrophoresis separation following chem. crosslinking. Upon reacting with homobifunctional N-hydroxysuccinimide-esters (NHS-esters), covalent linkages can be established between the primary amines of two neighboring antibody mols. The reaction conditions are optimized to achieve quant. crosslinking of only phys. associated monomers within an antibody dimer. The resulting crosslinked dimers, originating from either covalent or non-covalent antibody dimers, can then be separated from monomers by SDS electrophoresis. A com. microchip electrophoresis instrument is used for high speed separation, allowing each sample to be analyzed in about 1 min. This approach was applied to crude mammalian cell culture samples. Using a 96-well gel filtration spin column format, interfering species in the cell culture media were efficiently removed from the samples. This method is well suited to the purpose of high throughput antibody dimer quantitation during cell culture expression, including clone selection and cell culture development. The total dimer content, both covalent and non-covalent, can be determined for hundreds of crude samples in a few hours. The effects of different crosslinking conditions on the determined dimer levels, as well as of different antibody pI values, are discussed.
