原裝現(xiàn)貨|Imject Ovalbumin (in PBS)
Formulation: Protein lyophilized in phosphate buffer (pH 7.2) with proprietary stabilizer
Sufficient For: Numerous conjugation reactions with immunogens using a variety of crosslinking methods
Highlights:
Purified from chicken egg whites and lyophilized in phosphate buffered saline
Single polypeptide protein with molecular mass of 45,000 Daltons
Contains 20 lysine residues, most of which have primary amines that are capable of reacting with a conjugation reagent
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
