CellMosaic® has designed this personalized conjugation kit to work with any protein with a MW over 20 KDa and for protein labeling of a chemotherapeutic drug or toxin containing carboxylic acid (-COOH) functional groups. Using the kit components, the customer converts the carboxylic acid to an activated N-hydroxysuccinimide (NHS) ester, followed by reaction with the surface amino groups of the protein to form a stable amide bond. The final product is purified to remove any unreacted drug. 

This kit provides materials to label one protein. Scale of the reaction: 50 nmol.

Shipping policy: heat-sensitive, choose overnight (ships Mon.-Thur.) or 2-day delivery (ships Mon.-Wed.) at checkout.

Requirement for protein:

  • MW of the protein: >20 KDa (Lower MW of protein is fine, but need customization. Please contact us for the customization)
  • Amount required: 50 nmol (2 mg if the protein is 40 KDa) (Lower amount of protein is fine, but need customization. Please contact us for the customization)
  • Preferably >90% pure by gel electrophoresis or SEC HPLC analysis
  • Protein has some lysine residues

Requirement for Small Molecule

  • Preferably > 90% pure
  • Absence of primary or secondary amine (-NH2) groups
  • Preferably contains only one non-hindered aliphatic carboxylic acid (-COOH)
  • For molecule containing aromatic carboxylic acid, hindered aliphatic carboxylic acid, or hydroxyl (-OH) groups, please consult CellMosaic first before placing the order.

Key Features of this PerKit™

  • Offers a simple and easy way to label protein with any small molecule containing carboxylic acid
  • Fast and easy preparation: 4hr preparation and <30 minutes hands-on time
  • All reagents and supplies included for preparation and purification
  • Over 90% pure conjugated products by SEC
  • Options to choose tailored services at CellMosaic prior to and after conjugation

Prior to conjugation: you can upload your small molecule information when you place your order. CellMosaic will general a PerKit™ sheet containing calculation, chemical structure, MW of your final conjugate, and recommendation for the conjugation if there is some special feature of your molecule. 

After conjugation: you can choose to send your sample to CellMosaic for HPLC analysis.
