Drug Conjugation Kits and Solutions

Prepare your own custom drug-conjugates for screening and proof-of-concept with CellMosaic’s Personalized Kits (PerKit™)

CellMosaic is now providing PerKits™ to help our life science clients quickly evaluate their biologics of interest (antibodies, proteins, peptides, and oligos) with direct conjugations of a range of key payloads (chemotherapeutic drugs and toxins) and traditional linker chemistry. Kits are available in many configurations with a variety of conjugation strategies.

Some drug conjugation kits apply to a general payload with certain functional groups such as carboxylic acid and amine. Some supply the selected, standard linkage molecules conjugated to a selected payload, ready with the appropriate reactive modifications to directly attach the payload and linker to your specific biologics of interest. The kits are complete with all reagents and procedures for attaching the selected payload directly to your biologics and purifying the final drug conjugates. All you need to supply is your biologics and standard lab equipment.

Service: CellMosaic is a premier service provider, and offers our expertise in all drug conjugations-related services for projects with more complex chemistry, or projects requiring larger product volumes or tighter specifications of the resulting final product. CellMosaic’s services cover all standard, non-proprietary conjugations.

AqueaTether ™ Technology: In the event that an drug conjugate cannot be made using classical linkers or the effectiveness of the drug conjugates are compromised by the number of toxins loaded onto the antibody, AqueaTether ™ Therapeutics, a separate division of CellMosaic, has developed novel super-hydrophilic and high-loading AqueaTether ™ linkers specifically to solve these problems. To explore this opportunity and learn more about AqueaTether ™ platform technologies, please visit our website at aqttherapeutics.com
