Purification of Alkaline Phosphatase

8. An increase in the rate of progression of the bands down the column decreases the sharpness of the bands. On 'Zeo-Karb 215' (40-60 mesh/in.) a rate ofprogression of 10-15 cm./hr. gave satisfactory results. 9. Equations have been derived permitting the calculation ofthe proportion ofthe column occupied by a component, the width ofthe boundaries and the expected yield of pure components in sep...

Characterization of human foetal intestinal alkaline phosphatase

The molecular structure of human foetal intestinal alkaline phosphatase was defined by high-resolution two-dimensional polyacrylamide-gel electrophoresis and amino acid inhibition studies. Comparison was made with the adult form of intestinal alkaline phosphatase, as well as with alkaline phosphatases isolated from cultured foetal amnion cells (FL) and a human tumour cell line (KB). Two non-ide...

Purification of kidney alkaline phosphatase.

Chicken Intestinal Alkaline Phosphatase

Purified chicken intestinal alkaline phosphatase is active at pH 8 to 9, but becomes rapidly inactivated with change of pH to 6 or less. Also, a solution of the inactivated enzyme at pH 4.5 rapidly regains its activity at pH 8. In the range of pH 6 to 8 a solution of purified alkaline phosphatase consists of a mixture of active and inactive enzyme in equilibrium with each other. The rate of ina...
