PerKit™ BSA Universal 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 universal small molecule containing a carboxylic acid (-COOH) functional group. Using the kit components, the customer converts the carboxylic acid to an activated sulfo 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. Total amount of BSA included: 5 mg.

• Requirement for Small Molecule
Containing one carboxylic acid functional group
Total amount: ≥ 1.8 µmol
Preferably > 90% pure
Absence of primary or secondary amine (-NH2) groups
The presence of the hydroxide (-OH) group will not affect the labeling
