For procedures involved in labeling a functionalized biopolymer using a preactivated small molecule, we charge our client a standard price.

• Chemistry: Preactivated small molecules that can react with an amine, acid, aldehyde, hydrazine, hydroxyamine, maleimide/alkyl halide, and sulfhydryl functional group in a biopolymer.
• Specification: Less than 5% of unreacted small molecules (for example free dye) remain in the labeled biopolymer after a standard desalting.
• Procedure: After a buffer exchange (if necessary), labeling of biopolymer using small molecules followed by a standard desalting. Finally concentration and labeling ratio determination (if applicable).
• Price: Standard price includes materials and labor for labeling. Price does not include the cost of small molecule and biopolymer, small molecule activation and, if deemed necessary, biopolymer modification to introduce additional functional groups and extra linkers.
• Starting materials: Please check biopolymer and small molecule for ordering information.
• Note: Labeling ratio can be optimized at client's request.
