Abstract
An ovoglycoprotein has a molecular weight of 30,000 daltons which is determined by a matrix-assisted laser desorption ionization time-of-flight type mass spectrometer, an amino acid sequence of 15 residues from the N-terminal represented by Thr-Glu-Ser-Pro-Xaa-Ser-Ala-Pro-Leu-Val-Pro-Ala-Asp-Met-Asp (wherein Xaa represents a cysteine residue or an amino acid residue having a sugar chain linked thereto) (SEQ ID NO:1) and a sugar content of about 25% by weight and free of trypsin-inhibitory activity and a resolution agent for chromatography comprises a fixed phase which comprises a carrier and the foregoing ovoglycoprotein linked to the carrier. The agent for resolving optical isomers is not expensive, and is stable and highly resistant to deterioration by organic solvents, excellent in liquid-flow through properties, has a high sample-loading rate and permits efficient resolution of optical isomers of a chiral compound.
