Antibodies to small peptide/haptens are generally raised by coupling to a large carrier proteins such as KLH (Keyhole Limpet Hemocyanin). KLH mol wt ranges 3-7.5 million. It is used for carrier protein as it offers plenty of free amino, carboxyl and cysteines for coupling various peptides or haptens.Antibodies are produced to both KLH and the peptide/hapten. Anti-KLH may give non-specific signals in various immunoassays. Anti-KLH antibodies can be removed by solid phase immunoaffinity column chromatography over the KLH-Agarose affinity column or by adsorbing with KLH protein.Source:KLH, isolated from the hemolymphs of the molllusk Megathura crenulataStorage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
