Description générale

Keyhole limpet hemocyanin (KLH) is a large, multi-subunit, O2-carrying, metalloprotein. It is isolated from a marine snail species called Megathura crenulate.

Actions biochimiques/physiologiques

Keyhole limpet hemocyanin (KLH) exhibits immunostimulatory properties and stimulates both cell-mediated and humoral responses in animals and humans. It serves as a vaccine adjuvant and facilitates protein conjugation. In addition, KLH acts as a carrier protein to produce antibodies as well as haptens such as peptides and oligosaccharides. It is also used in the treatment of bladder cancer.

Conditionnement

Please refer to vial label for lot-specific concentration.

Avertissement

Toxicity: Standard Handling (A)

Forme physique

In 10 mM MgSO₄, 5 mM BES buffer, 0.9% NaCl, pH 6.5. Sterile-filtered.

Notes préparatoires

KLH is an extremely large protein complex that has a tendency to aggregate and precipitate from solutions. Use a buffer when diluting KLH and maintain the magnesium concentration at ≥10 mM. Store KLH solutions at 4°C. DO NOT freeze, vortex or agitate to dissolve KLH. Freezing or agitating KLH will cause protein aggregation and precipitation.

Keyhole limpet hemocyanin (KLH) is used as a vaccine adjuvant, as a carrier protein for small haptens, and as a treatment for bladder cancer. Immunization with KLH produces antibodies to tumor-associated carbohydrate antigens (TACAs) in animals, and these antibodies have

Keyhole limpet hemocyanin (KLH) attracts biomedical interest because of its remarkable immunostimulatory properties. Currently, KLH is used as vaccine adjuvant, carrier protein for haptens and as local treatment for bladder cancer. Since a quantitative human anti-KLH assay is lacking, it
