This is a Personalized conjugation kit (PerKit™) for Cyanine 3 dye labeling of a small molecule containing carboxylic acid (-COOH) functional groups (1 mg scale). Using the kit components, the customer converts the carboxylic acid (not supplied) to an activated N-hydroxysuccinimide (NHS) ester, followed by reaction with an equivalent amount of the amine cyanine 3 dye. 

Requirement for Small Molecule

  • Preferably > 90% pure
  • Absence of primary or secondaryamine (-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 small molecules with COOH: 2 h preparation and <30 minutes hands-on time
  • Quantitative reaction with stable bond
  • 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 your molecule has special features. 

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