Characterisation of galactosyltransferase isoforms by ion-exchange and lectin affinity chromatography.
Galactosyltransferase (GT) was isolated from human malignant ascitic fluid, and the ion-exchange and lectin affinity chromatographic behaviour of the two isoforms, GTI and GTII, investigated. The effect of neuraminidase on the binding to DEAE-Sephacel and various lectins suggests that GTII, the so-called cancer-specific isoform, is a more sialylated form of GTI.
