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. CellMosaic® has designed this personalized BSA conjugation kit 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
• Preferably > 90% pure
• Absence of primary or secondary amine (-NH2) groups
• The presence of the hydroxide (-OH) group will not affect the labeling

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 h 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 conjugation: you can upload your small molecule information when you place your order. CellMosaic will check if your molecule is compatible with this kit. 

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