PerKit™ Protein Small Molecule Acid Conjugation Kit

This is a personalized conjugation kit (PerKit™) works with any protein with a MW over 20 KDa and any small molecule containing carboxylic acid (-COOH) functional groups. Using the kit components, our customers convert 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 desalted to remove any unreacted small molecule acid.

This kit provides materials to label 15-50 nmole of one protein sample (≥20 KDa)

• Requirements for Small Molecules
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 us 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: 4 h preparation and <30 minutes hands-on time
All reagents and supplies included for preparation and purification
Over 90% pure conjugated products by SEC
