Thermo Scientific™ Imject™ Blue Carrier™ Protein

Description

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.

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)
