Title:
CONJUGATES OF CHOLINESTERASE MOIETY AND POLYMER
Document Type and Number:
Japanese Patent JP2017205120
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide methods for preparing di-conjugated cholinesterase dimer conjugates.SOLUTION: A method of the invention comprises the steps of: (a) combining a reagent composition comprising a plurality of thiol-selective polymer reagent molecules with a composition comprising a plurality of cholinesterase dimer molecules under a conjugate forming condition; (b) subjecting the conjugate mixture to a reducing condition; (c) separating reduced mono-conjugated cholinesterase monomers from the reduced mixture; and (d) removing the reducing condition from the composition containing the reduced mono-conjugated cholinesterase monomers.SELECTED DRAWING: None
