For conjugating one biopolymer to another biopolymer using a heterobifunctional crosslinker, we charge our client a standard price.

• Chemistry: Typical preparation of conjugates using a heterobifunctional crosslinker through NHS ester-Maleimide, reductive amination, oxime, and hydrozone formation.
• Specification:A pool of heterogeneous products containing single or multi-site labeling per molecule.
• Procedure: After a buffer exchange (if necessary) 1st biopolymer labeling using the heterobifunctional crosslinking reagent of choice. Then excess crosslinking reagents removal by gel filtration and labeling ratio/efficiency determination (or functional group test if applicable), followed by conjugation of 2nd biopolymer.
• Price: Standard price includes materials and labor for conjugation. Price does not include the cost of biopolymers and, if deemed necessary biopolymer modification to introduce additional functional groups and extra linkers.
• Starting materials: Please check check biopolymer for ordering information.
