title: Kasahara-variant alkaline phosphatase in a renal cell carcinoma.
abstract: Electrophoretically Kasahara-variant alkaline phosphatase we found in a renal cell carcinoma tissue. This enzyme electrophoresed more quickly than liver alkaline phosphatase but more slowly than Kasahara isoenzyme. Neuraminidase treatment of the enzyme caused retardation of electrophoretic mobility which was the same as that of neuraminidase-treated Kasahara isoenzyme. The enzymic properties of this variant enzyme such as inhibition by L-phenylalanine, L-homoarginine, L-leucine, EDTA and urea are consistent with those of Kasahara isoenzyme. On Ouchterlony double diffusion, the precipitin lines of Kasahara and Kasahara-variant enzymes produced by antibody to Kasahara isoenzyme fused completely. These facts may mean that Kasahara-variant isoenzyme is different from the Kasahara one in terminal sialic acid content.
