Description

Prepare hapten-carrier conjugates to generate antibodies using this convenient and highly immunogenic, cationized BSA carrier protein.

Thermo Scientific™ Imject Cationized Bovine Serum Albumin (cBSA) functions as an easy-to-use and highly immunogenic carrier protein for preparing antigens for use in antibody production.

Imject cBSA is prepared by modifying native BSA with excess ethylenediamine, essentially capping all negatively-charged carboxyl groups with positively-charged primary amines. The result is a highly positively-charged protein (pI > 11) that has significantly increased immunogenicity compared to native BSA. In addition, the increased number of primary amines provides for a greater number of antigen molecules to be conjugated with typical crosslinking methods.

Imject cBSA is an excellent choice for immunogen preparation when greater immunogenicity is needed relative to BSA but conditions are not amenable to using keyhole limpet hemocyanin (KLH) or Blue Carrier™ Protein.

Highlights:

  • Convenient – purified bovine serum albumin (BSA) that is cationized and supplied lyophilized in PBS

  • Single polypeptide – modified BSA protein with molecular mass greater than 67,000 daltons

  • Multiple conjugation sites – contains 59 lysine residues, plus numerous other primary amines added by cationization, most of which are capable of reacting with a conjugation reagent to attach antigens

  • Net positive charge – confers solubility in conditions not suitable for the negatively-charged native BSA

  • Immunogenic – significantly greater immunogenicity than native BSA because the positively charged protein is processed differently by the immune-response system
