Thermo Scientific™ Imject™ Blue Carrier™ Protein

Easily prepare effective immunogens with the highly-soluble, mollusk-derived hemocyanin and complete hapten-carrier conjugation kit.

Thermo Scientific™ Blue Carrier Protein is a highly-soluble, mollusk-derived hemocyanin formulated in convenient package sizes and a complete kit for carbodiimide (EDC-mediated) hapten-carrier conjugation via amine and carboxyl groups.

Blue Carrier Protein is a purified preparation of Concholepas concholepas hemocyanin (CCH). The large protein exhibits most of the same immunogenic properties as the popular carrier protein, keyhole limpet hemocyanin (KLH). However, its signficantly better solubility provides greater flexibility in immunogen preparation protocols by allowing a broader range of buffer and pH conditions for coupling peptides, proteins and other haptens using classical crosslinkers such as glutaraldehyde, Sulfo-SMCC and EDC.

Highlights:

• Convenient packages – choose lyophilized Blue Carrier Protein or complete EDC conjugation kit

• High-yield conjugation – each molecule of CCH contains hundreds of primary amines available for coupling haptens via EDC or NHS ester crosslinkers

• Validated quality – the immunogenic carrier protein is specially purified to ensure uniform chemical structure and solubility for consistent performance

• Superior solubility – increased solubility compared to KLH allows Blue Carrier Protein to be used in a broader range of conjugation protocols to accommodate unusual or poorly soluble haptens

• Highly immunogenic – provides essentially the same level of immunogenicity and phylogenetic distance as keyhole limpet hemocyanin (KLH)
