Description

Description générale

Keyhole limpet hemocyanin (KLH) is a large, multi-subunit, O2-carrying, metalloprotein. This high molecular weight glycoprotein is extracted from a marine snail species called Megathura crenulate.

Application

Hemocyanin, Keyhole Limpet, Megathura crenulata, high purity, endotoxin-free, sterile-liquid has been used as an antigen to test the polyreactivity of monoclonal antibody (mAb) using enzyme-linked immunosorbent assay(ELISA). It has also been used to immunize animals to study KLH-specific ex vivo recall responses and specific T-cell dependent antibody response (TDAR) in monkeys.

Actions biochimiques/physiologiques

Keyhole limpet hemocyanin (KLH) stimulates both cell-mediated and humoral responses in animals and humans. It elicits immunostimulatory properties and also functions as a vaccine adjuvant. KLH serves as a carrier protein to produce antibodies and haptens like peptides and oligosaccharides. It is used to treat bladder cancer.

Conditionnement

Please refer to vial label for lot-specific concentration.

Avertissement

Toxicity: Standard Handling (A)

Forme physique

In 83 mM sodium phosphate, 150 mM NaCl, pH 7.2.

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.
