PerKit™ BSA Small Molecule Acid Conjugation Kit

Bovine serum albumin (also known as BSA or "Fraction V") is a serum albumin protein derived from cows. BSA is often used as a carrier protein for immunization. This personalized BSA conjugation kit is designed to work with any small molecule containing an aliphatic carboxylic acid (-COOH) functional group. 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 small molecule acid.

This kit provides materials to perform one BSA labeling reaction. Total amount of BSA included: 5 mg.

• Requirement for Small Molecule
Preferably > 90% pure
Total amount: 20 µmol
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 use CM52425 (PerKit™ BSA Universal Small Molecule Acid Conjugation Kit) instead.

• Key Features of this PerKit™
Offers a simple and easy way to label BSA with any small molecule containing carboxylic acid
Fast and easy preparation: 4 hr preparation and <30 minutes hands-on time
All reagents and supplies included for preparation and purification
Over 90% pure conjugated products by SEC HPLC
