^ Although ovomucoid has been separated from egg white by a number of methods, the Lineweaver and Murray (1947) trichloroacetic acid-acetone procedure has probably been the most widely used in recent years. It is the method used commonly for commercial production (see Melamed, 1966, and Montreuil et al., 1965, for reviews). Preparations of ovomucoid obtained by this method, including those from commercial sources, may contain up to 20% of other egg-white proteins as impurities. Among those identified are lysozyme (Tomimatsu et al., 1966; Donovan, 1967), ovo-inhibitor (Feeney et al., 1963; Tomimatsu et al., 1966; Ket-terer’s, 1965), glycoprotein (Montreuil et al., 1965), ovalbumins, and probably flavoprotein (see below). Melamed (1966) has summarized the methods used to purify Lineweaver-Murray (1947) ovomucoid. Chromatography on ion-exchange celluloses is the generallyaccepted procedure even though doubt has been raisedconcerning the stability of the sialic acid residues of ovomucoid at thelow pH encountered during chromatography on carboxymethyl-cellulose (Rhodes et al., 1960; Chatterjee and Montgomery,
