Isoelectric focusing of human liver alkaline phosphatase

Isoelectric Focusing of Human Liver

1. Isoelectric focusing of human liver alkaline phosphatase in a sucrose density gradient with LKB Ampholine as carrier ampholytes is described. 2. Problems due to the chelating properties of the ampholytes and the pH gradient were examined. 3. A reactivation procedure to counter these effects was devised that can probably be used for other alkaline phosphatases. 4. The isoelectric point of hum...

Resolution of alkaline phosphatase isoenzymes in serum by isoelectric focusing in immobilized pH gradients.

This new method for fractionation of serum alkaline phosphatase isoenzymes is based on isoelectric focusing on a mixed-type polyacrylamide support containing an immobilized pH gradient with a superimposed carrier-ampholyte gradient. All known forms of alkaline phosphatase are separated in an Immobiline pH 3.5-6.0 gradient, the sample being applied into pockets cast on a pH 8.0 plateau. Sharp zy...

Alkaline Phosphatase in Serum is a Marker of Human Toxocariasis

Background: The present study was carried out on the human population of Kashmir valley to evaluate the status of the biochemical parameters of infected population. Materials and Methods: Blood samples were collected from 514 individuals, 298 (57.97%) males and 216 (42.02%) females, 187 (36.38%) were found sero-positive for human toxocariasis. Results: Alkaline phosphatase level was found highe...

Structure of the human liver/bone/kidney alkaline phosphatase gene.

In man, there are multiple forms of alkaline phosphatase encoded by at least three homologous genes: placental, intestinal, and liver/bone/kidney. This report describes the characterization of the human liver/bone/kidney alkaline phosphatase locus. The gene appears to exist as a single copy in the haploid genome and is comprised of 12 exons distributed over more than 50 kilobases. In liver, kid...
