Maleimide Activated R-Phycoerythrin Summary

Maleimide-activated R-Phycoerythrin is designed to facilitate the conjugation of RPhycoerythrin to proteins, peptides and ligands that contain sulfhydryl (-SH) groups. The reactive maleimide group that has been added to the R-Phycoerythrin allows conjugation reaction is carried out in the pH range 6.5-7.5, creating a stable thio-ether link.

Packaging, Storage & Formulations

Store at -20C. Avoid freeze-thaw cycles.
Supplied as freeze dried formulations
No Preservative

Molecules that do not contain -SH groups can be chemically modified to introduce the required thiol functionality. In the case of antibodies, disulfide (S-S) bridges may also be cleaved to release free thiols.

This prodcut is manufacture by Innova Biosciences.


Maledimide and periodate activated labels are designed to facilitate the conjugation of the desired label to either antibodies, proteins, peptides or ligands that contain a sulfhydryl (-SH) or amine (-NH2) group respectively. The reactive maleimide or periodate groups that have been added to the label allows conjugation reactions to be performed very efficiently at physiological pH for superior performance.

Innova Biosciences activated labels are supplied as stable freeze dried formulations, with all material being rigorously QC tested using thiolated biomolecules to ensure high conjugation efficiency.


This product is for research use only and is not approved for use in humans or in clinical diagnosis. Support products are guaranteed for 6 months from date of receipt.
