BLUE CARRIER®
in 50% Glycerol
This non-sterile solution contains hemocyanin derived from the hemolymph of the Chilean mollusk Concholepas concholepas. The deep blue color of BLUE CARRIER® preparations results from the oxygenated form of this copper-containing protein.
Worldwide presence:
Since its introduction to the world market 20 years ago by our Company, more than 15 kilograms of protein have been purchased by universities, research institutes, and biotechnology companies around the world. Millions of immunizations have been successfully performed. Hence, most of the antibodies commercially available for biomedical research in the world have been produced using BLUE CARRIER® .
Immunogenicity:
BLUE CARRIER® (often called Blue Carrier Protein) is a highly immunogenic carrier protein used to stimulate an immune response when developing antibodies against peptides and haptens. It is best known as a premium alternative to Keyhole Limpet Hemocyanin (KLH) for its higher solubility and stability in conjugation protocols. Mollusk-derived hemocyanins are highly immunogenic in vertebrates due to their large molecular size (Mr 8.0 × 106), glycosylations, complex structure, and distant phylogenetic origin.
Conjugation to peptides and haptens:
BLUE CARRIER® contains several epsilon-amino groups from lysine and carboxylic groups (Asp or Glu). These allow conjugation with peptides and haptens by traditional methods such as glutaraldehyde and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDCI), as well as via sulfhydryl groups introduced into the peptides.
Solubility and stability:
Hemocyanins are generally marketed as solid, freeze-dried products, and exhibit reduced solubility upon resuspension, primarily due to their high molecular weight. In contrast, BLUE CARRIER® maintains high solubility because its collection and purification processes yield a pure, blue, transparent solution suspended in an optimal buffer. Concholepas hemocyanin demonstrates exceptional stability and solubility.
