        Zein is a prolamine; an alcohol-soluble protein present
        in amounts of 2.5-10% (dry basis) in corn. Zein is a
        common component used in the manufacture of
        plastics, paper coatings, adhesives, substitutes for
        shellac, laminated board, and solid color printing films.
        Zeins are the main storage proteins found in the seeds
        of maize. Following protein translation, the zeins are
        stored in the rough endoplasmic reticulum
        (ER)-derived protein bodies. The accumulation of zein
        in these ER-derived protein bodies results in the
        formation of the endosperm - the food storage body of
        seeds.
        Currently, there are four classes of zein: α, β, γ, and δ.
        These classes are expressed sequentially in maize
        and are found to interact with each other for stability.
        Zein from corn was reported to be approximay
        35% α-zein, which includes 2 prominent bands of
        22 and 24 kDa. β-zein fails to enter an SDS-PAGE gel
        without reduction. Reducing SDS-PAGE analysis
        shows that β-zein has 3 major bands of 24, 22, and
        14 kDa.1 The amino acid sequences have been
        published.2

        For Laboratory Use Only. Not for drug, household or
        other uses.
        Preparation Instructions
        Zein is soluble in aqueous alcohols, glycols, ethyl
        ether, furfuryl alcohol, tetrahydrofurfuryl alcohol, and
        aqueous alkaline solutions of pH 11.5 or greater. Zein
        is insoluble in water, acetone, and anhydrous alcohols
        (except methanol).
        Storage/Stability
        Zein is rapidly denatured in solution and becomes
        insoluble.
