title: A rat epididymal sialoglycoprotein with alpha-lactalbumin activity.
abstract: A major sialoglycoprotein from rat epididymal fluid was radiolabeled by NaIO4/[3H]KBH4 method and purified by chromatography using DEAE-Sepharose and chromatofocusing columns. Its Mr was 21,000 and its pI value was 4.9. Since it possessed a high sialic acid content and an alpha-lactalbumin-like activity, it was proposed to be a sialylated form of epididymal alpha-lactalbumin-like protein.
