title: High performance liquid chromatography of integral glycoproteins of peripheral nerve myelin.
abstract: Peripheral nerve myelin contains a large quantity of integral glycoproteins, such as PO and PASII protein. The present paper reports a fast and sensitive method for separation of these glycoproteins. High performance liquid chromatography (HPLC) with TSK-GEL 3000 SW column in the presence of sodium dodecyl sulfate (SDS) or lithium dodecyl sulfate (LDS) was used. Whereas the separation of PO and PASII was inadequate with low concentrations of the detergent, better separation profiles were obtained with high concentrations (1-2%) of the detergent in 0.1 M phosphate buffer. The two glycoproteins were able to be purified by rechromatography. High concentration of the detergent presumably diminished interaction between these glycoproteins. LSD-phosphate, SDS-lithium citrate or SDS-Tris buffer as an eluent was also compared with SDS-phosphate system. This method will be applicable to the detection and purification of proteins from myelin or other organelles.
