Description
Quantity: 5 x 2 mg
Unit Size: Each
The high-quality mariculture KLH is rendered sulfhydryl-reactive by chemical modification with Sulfo-SMCC crosslinker, and the resulting maleimide-activated protein is then stabilized and lyophilized in phosphate buffer. Maleimide groups form covalent crosslinks with sulfhydryl (-SH) moieties on cysteine residues of peptides and other thiol-containing haptens. Numerous antigen molecules can be conjugated to each KLH molecule to make them highly immunogenic and increase the likelihood of eliciting immunized animals to produce high-titer antisera to the epitopes of interest. Select from among several package sizes of activated KLH protein, or choose the complete conjugation kit that includes optimized buffers and trouble-free spin desalting columns. Highlights:
• Convenient packages– choose stabilized, lyophilized Maleimide-Activated mcKLH or a complete immunogen conjugation kit
• Optimized activation– specifications require that each lot is activated with more than 400 moles of sulhydryl-reactive maleimide per mole of KLH, ensuring consistently high levels of conjugation
• Sulfhydryl-reactive – engineered for conjugating cysteine-containing peptide antigens to make effective immunogens for high-titer antibody production
• Simple, rapid procedure– complete the hapten-carrier conjugation reaction in two hours to yield sufficient immunogen for several injections and booster immunizations of host animals
• High-quality carrier protein– KLH is isolated from the mollusk Megathura crenulata (keyhole limpet); mcKLH is a high-quality form of KLH that is harvested from limpets grown in mariculture
• Highly immunogenic– KLH has a high molecular mass (0.5 to 13 million daltons; aggregates of 350 and 390kDa subunits) and elicits a stronger immune response than BSA or ovalbumin
• Excellent solubility– our preparations of mariculture KLH are more soluble than typical forms and we also offer a PEGylated form for even greater hydrophilicity and solubility Includes:Kit contains stabilized, lyophilized Maleimide-Activated mcKLH (in PBS with stabilizer), buffers and desalting columns to easily prepare ready-to-use immunogens for immunization
