    名称: 原装进口|Imject Maleimide-Activated Ovalbumin
    This product consists of purified, carrier-grade ovalbumin that has been modified with SMCC crosslinker to attach maleimide groups capable of forming covalent crosslinks with sulfhydryl (-SH) moieties on cysteine residues of peptides and other molecules. Immunogens are easily prepared from peptide antigens that have been engineered with a terminal cysteine residue as a precise conjugation point. Several antigen molecules can be attached per carrier protein molecule without blocking intended epitopes by crosslinking to primary amines or carboxylates within the peptide sequence.
    Highlights:
    Contains 14 aspartic acid and 33 glutamic acid residues whose carboxyl groups account for the net negative charge (pI 4.63) of OVA
    Not as immunogenic as keyhole limpet hemocyanin (KLH) but more soluble in DMSO (dimethyl sulfoxide) for applications that require this solvent
    Useful as an irrelevant protein carrier for antibody screening and immunoassays after using KLH as the carrier protein to generate the immune response against the hapten
    Maleimide-Activated Ovalbumin, supplied lyophilized in PBS (pH 7.2) with stabilizer
    Activated with 5 to 15 moles of maleimide per mole of ovalbumin
    Ideal for conjugating cysteine-containing peptide antigens to make immunogen or screening target
    Conjugation reaction complete in 2 hours; results in stable, covalent thioether bonds
    Single polypeptide protein with molecular mass of 45,000 Daltons
